Processing massive amount of data with Map Reduce using Apache Hadoop - Indi...IndicThreads
Session presented at the 2nd IndicThreads.com Conference on Cloud Computing held in Pune, India on 3-4 June 2011.
http://CloudComputing.IndicThreads.com
Abstract: The processing of massive amount of data gives great insights into analysis for business. Many primary algorithms run over the data and gives information which can be used for business benefits and scientific research. Extraction and processing of large amount of data has become a primary concern in terms of time, processing power and cost. Map Reduce algorithm promises to address the above mentioned concerns. It makes computing of large sets of data considerably easy and flexible. The algorithm offers high scalability across many computing nodes. This session will introduce Map Reduce algorithm, followed by few variations of the same and also hands on example in Map Reduce using Apache Hadoop.
Speaker: Allahbaksh Asadullah is a Product Technology Lead from Infosys Labs, Bangalore. He has over 5 years of experience in software industry in various technologies. He has extensively worked on GWT, Eclipse Plugin development, Lucene, Solr, No SQL databases etc. He speaks at the developer events like ACM Compute, Indic Threads and Dev Camps.
A MapReduce job usually splits the input data-set into independent chunks which are processed by the map tasks in a completely parallel manner. The framework sorts the outputs of the maps, which are then input to the reduce tasks. Typically both the input and the output of the job are stored in a file-system.
Hadoop became the most common systm to store big data.
With Hadoop, many supporting systems emerged to complete the aspects that are missing in Hadoop itself.
Together they form a big ecosystem.
This presentation covers some of those systems.
While not capable to cover too many in one presentation, I tried to focus on the most famous/popular ones and on the most interesting ones.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

4. You Say, “tomato…”
Google calls it: Hadoop equivalent:
MapReduce Hadoop
GFS HDFS
Bigtable HBase
Chubby Zookeeper
5. Some MapReduce Terminology
Job – A “full program” - an execution of a
Mapper and Reducer across a data set
Task – An execution of a Mapper or a
Reducer on a slice of data
a.k.a. Task-In-Progress (TIP)
Task Attempt – A particular instance of an
attempt to execute a task on a machine
6. Terminology Example
Running “Word Count” across 20 files is
one job
20 files to be mapped imply 20 map tasks
+ some number of reduce tasks
At least 20 map task attempts will be
performed… more if a machine crashes,
etc.
7. Task Attempts
A particular task will be attempted at least once,
possibly more times if it crashes
If the same input causes crashes over and over, that
input will eventually be abandoned
Multiple attempts at one task may occur in
parallel with speculative execution turned on
Task ID from TaskInProgress is not a unique identifier;
don’t use it that way
9. Node-to-Node Communication
Hadoop uses its own RPC protocol
All communication begins in slave nodes
Prevents circular-wait deadlock
Slaves periodically poll for “status” message
Classes must provide explicit serialization
10. Nodes, Trackers, Tasks
Master node runs JobTracker instance,
which accepts Job requests from clients
TaskTracker instances run on slave nodes
TaskTracker forks separate Java process
for task instances
11. Job Distribution
MapReduce programs are contained in a Java
“jar” file + an XML file containing serialized
program configuration options
Running a MapReduce job places these files
into the HDFS and notifies TaskTrackers where
to retrieve the relevant program code
… Where’s the data distribution?
12. Data Distribution
Implicit in design of MapReduce!
All mappers are equivalent; so map whatever
data is local to a particular node in HDFS
If lots of data does happen to pile up on
the same node, nearby nodes will map
instead
Data transfer is handled implicitly by HDFS
13. Configuring With JobConf
MR Programs have many configurable options
JobConf objects hold (key, value) components
mapping String ’a
e.g., “mapred.map.tasks” 20
JobConf is serialized and distributed before running
the job
Objects implementing JobConfigurable can
retrieve elements from a JobConf
15. Job Launch Process: Client
Client program creates a JobConf
Identify classes implementing Mapper and
Reducer interfaces
JobConf.setMapperClass(), setReducerClass()
Specify inputs, outputs
FileInputFormat.addInputPath(),
FileOutputFormat.setOutputPath()
Optionally, other options too:
JobConf.setNumReduceTasks(),
JobConf.setOutputFormat()…
16. Job Launch Process: JobClient
Pass JobConf to JobClient.runJob() or
submitJob()
runJob() blocks, submitJob() does not
JobClient:
Determines proper division of input into
InputSplits
Sends job data to master JobTracker server
17. Job Launch Process: JobTracker
JobTracker:
Inserts jar and JobConf (serialized to XML) in
shared location
Posts a JobInProgress to its run queue
18. Job Launch Process: TaskTracker
TaskTrackers running on slave nodes
periodically query JobTracker for work
Retrieve job-specific jar and config
Launch task in separate instance of Java
main() is provided by Hadoop
19. Job Launch Process: Task
TaskTracker.Child.main():
Sets up the child TaskInProgress attempt
Reads XML configuration
Connects back to necessary MapReduce
components via RPC
Uses TaskRunner to launch user process
20. Job Launch Process: TaskRunner
TaskRunner, MapTaskRunner,
MapRunner work in a daisy-chain to
launch your Mapper
Task knows ahead of time which InputSplits it
should be mapping
Calls Mapper once for each record retrieved
from the InputSplit
Running the Reducer is much the same
21. Creating the Mapper
You provide the instance of Mapper
Should extend MapReduceBase
One instance of your Mapper is initialized
by the MapTaskRunner for a
TaskInProgress
Exists in separate process from all other
instances of Mapper – no data sharing!
23. What is Writable?
Hadoop defines its own “box” classes for
strings (Text), integers (IntWritable), etc.
All values are instances of Writable
All keys are instances of
WritableComparable
24. Getting Data To The Mapper
Input file
InputSplit InputSplit InputSplit InputSplit
Input file
RecordReader RecordReader RecordReader RecordReader
Mapper
(intermediates)
Mapper
(intermediates)
Mapper
(intermediates)
Mapper
(intermediates)
InputFormat
25. Reading Data
Data sets are specified by InputFormats
Defines input data (e.g., a directory)
Identifies partitions of the data that form an
InputSplit
Factory for RecordReader objects to extract
(k, v) records from the input source
26. FileInputFormat and Friends
TextInputFormat – Treats each ‘n’-
terminated line of a file as a value
KeyValueTextInputFormat – Maps ‘n’-
terminated text lines of “k SEP v”
SequenceFileInputFormat – Binary file of
(k, v) pairs with some add’l metadata
SequenceFileAsTextInputFormat – Same,
but maps (k.toString(), v.toString())
27. Filtering File Inputs
FileInputFormat will read all files out of a
specified directory and send them to the
mapper
Delegates filtering this file list to a method
subclasses may override
e.g., Create your own “xyzFileInputFormat” to
read *.xyz from directory list
28. Record Readers
Each InputFormat provides its own
RecordReader implementation
Provides (unused?) capability multiplexing
LineRecordReader – Reads a line from a
text file
KeyValueRecordReader – Used by
KeyValueTextInputFormat
29. Input Split Size
FileInputFormat will divide large files into
chunks
Exact size controlled by mapred.min.split.size
RecordReaders receive file, offset, and
length of chunk
Custom InputFormat implementations may
override split size – e.g., “NeverChunkFile”
30. Sending Data To Reducers
Map function receives OutputCollector
object
OutputCollector.collect() takes (k, v) elements
Any (WritableComparable, Writable) can
be used
By default, mapper output type assumed
to be same as reducer output type
32. Sending Data To The Client
Reporter object sent to Mapper allows
simple asynchronous feedback
incrCounter(Enum key, long amount)
setStatus(String msg)
Allows self-identification of input
InputSplit getInputSplit()
34. Partitioner
int getPartition(key, val, numPartitions)
Outputs the partition number for a given key
One partition == values sent to one Reduce
task
HashPartitioner used by default
Uses key.hashCode() to return partition num
JobConf sets Partitioner implementation
35. Reduction
reduce( K2 key,
Iterator<V2> values,
OutputCollector<K3, V3> output,
Reporter reporter)
Keys & values sent to one partition all go
to the same reduce task
Calls are sorted by key – “earlier” keys are
reduced and output before “later” keys
