Exploring Innovations in Data Repository Solutions - Insights from the U.S. G...Globus
The U.S. Geological Survey (USGS) has made substantial investments in meeting evolving scientific, technical, and policy driven demands on storing, managing, and delivering data. As these demands continue to grow in complexity and scale, the USGS must continue to explore innovative solutions to improve its management, curation, sharing, delivering, and preservation approaches for large-scale research data. Supporting these needs, the USGS has partnered with the University of Chicago-Globus to research and develop advanced repository components and workflows leveraging its current investment in Globus. The primary outcome of this partnership includes the development of a prototype enterprise repository, driven by USGS Data Release requirements, through exploration and implementation of the entire suite of the Globus platform offerings, including Globus Flow, Globus Auth, Globus Transfer, and Globus Search. This presentation will provide insights into this research partnership, introduce the unique requirements and challenges being addressed and provide relevant project progress.
Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.

2. Purpose
• This guide describes the setup of a standalone HBase instance running
against the local filesystem/HDFS.
• This is not an appropriate configuration for a production instance of
HBase, but will allow you to experiment with HBase.
• This section shows you how to create a table in HBase using the hbase
shell CLI, insert rows into the table, perform put and scan operations
against the table, enable or disable the table, and start and stop HBase.
2
3. Required Software
• Java™ HBase requires that a JDK be installed.
http://hbase.apache.org/book.html#java
• Choose a download site from this list of Apache Download Mirrors.
• Click on the suggested top link.
• Click on the folder named stable and then download the binary file that ends
in .tar.gz to your local filesystem.
• Be sure to choose the version that corresponds with the version of Hadoop you
are likely to use later. (hbase-0.98.3-hadoop2-bin.tar.gz.)
3
4. Prepare to Start the Hadoop Cluster (Cont.)
• Like HDFS, HBase has also 3 running mode:
• Standalone HBase (Setup of a standalone HBase instance running against the local filesystem)
• In standalone mode HBase runs all daemons within this single JVM, i.e. the HMaster, a single
HRegionServer, and the ZooKeeper daemon.
• Using HBase with a local filesystem does not guarantee durability.
• Prior to HBase 0.94.x, HBase expected the loopback IP address to be 127.0.0.1. Ubuntu and some other
distributions default to 127.0.1.1 and this will cause problems for you.
• Pseudo-Distributed Local Install
• HBase still runs completely on a single host, but each HBase daemon (HMaster, HRegionServer, and
Zookeeper) runs as a separate process.
• Fully Distributed
4
5. Prepare to Start the HBase-Standalone
• Unpack the downloaded HBase distribution. In the distribution, edit the
file conf/hbase-env.sh, uncomment the line starting with JAVA_HOME, and
set it to the appropriate location for your operating system:
# set to the root of your Java installation
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0
5
6. Prepare to Start the HBase-Standalone (Cont.)
• Edit conf/hbase-site.xml, which is the main HBase configuration file.
• At this time, you only need to specify the directory on the local filesystem where HBase and
ZooKeeper write data.
• By default, a new directory is created under /tmp.
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///home/testuser/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/testuser/zookeeper</value>
</property>
</configuration>
6
7. Prepare to Start the HBase-Standalone (Cont.)
• The bin/start-hbase.sh script is provided as a convenient way to start
HBase.
• Use the jps command to verify that you have one running process called Hmaster.
• Remember that in standalone mode HBase runs all daemons within this single JVM, i.e. the
HMaster, a single HRegionServer, and the ZooKeeper daemon.
7
8. Pseudo-Distributed Configuration
• You can re-configure HBase to run in pseudo-distributed mode:
• Stop HBase if it is running.
• Configure HBase:
• Edit the hbase-site.xml configuration.
• This directs HBase to run in distributed mode,
with one JVM instance per daemon.
• Next, change the hbase.rootdir from the local
filesystem to the address of your HDFS instance, using the hdfs://// URI syntax.
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
8
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:8020/hbase</value>
</property>

10. 1- Start HBase daemon
start-hbase.sh
2- Start HBase shell
hbase shell

Create a table called Book whose schema will able to house book's title, description, author's
first and last names. Book's title and description should be grouped as they will saved
retrieved together. Author's first and last name should also be grouped.
(hint: since title and description need to be grouped together and so do author's first and last
name, it would be wise to place them into 2 families such as info and author. Then title and
description will become columns of info family and first and last columns of author family).
3-
create 'Book', {NAME=>'info'}, {NAME=>'author'}
11. 4- Add the following information to Book table:
11
put 'Book', '1', 'info:title', 'Faster than the speed love'
put 'Book', '1', 'info:description', 'Long book about love'
put 'Book', '1', 'author:first', 'Brian'
put 'Book', '1', 'author:last', 'Dog'
put 'Book', '2', 'info:title', 'Long day'
put 'Book', '2', 'info:description', 'Story about Monday'
put 'Book', '2', 'author:first', 'Emily'
put 'Book', '2', 'author:last', 'Blue'
put 'Book', '3', 'info:title', 'Flying Car'
put 'Book', '3', 'info:description', 'Novel about airplanes'
put 'Book', '3', 'author:first', 'Phil'
put 'Book', '3', 'author:last', 'High'
12. 12
Count the number of rows. Make sure that every row is printed to
the screen as it being counted.
5-
count 'Book', INTERVAL => 1
6- Retrieve an entire record with ID 1
get 'Book', '1'
7- Only retrieve title and description for record with ID 3.
get 'Book', '3', {COLUMNS=>['info:title', 'info:description']}
13. 13
Change the last name of an author for the record with title Long
Day to Happy.
8-
put 'Book', '2', 'author:last', 'Happy'
# to verify select the record
get 'Book', '2', {COLUMNS=>'author:last'}
# to display both versions
get 'Book', '2', {COLUMNS=>'author:last', VERSIONS=>3}get 'Book', '3',
{COLUMNS=>['info:title', 'info:description']}
• Display the record on the screen to verify the change.
• Display both new and old value. You should be able to see both Blue and
Happy. Why is that?
14. 14
scan 'Book'
9- Display all the records to the screen.
scan 'Book', {COLUMNS=>['info:title', 'author:last']}
scan 'Book', {COLUMNS=>['info:title','info:description'], LIMIT=>'2'}

10- Display title and author's last name for all the records.
11- Display title and description for the first 2 records.
15. 15
Book table is hosted via 1 Region Server and there is only 1 Region.
There are no start or end keys for that region because there is only 1
region. It has 2 families info and author. There is no compression set
for both families, and replication is set to 3.
13- Check the detailed status of your cluster via HBase shell.
