Terraform
This document discusses infrastructure as code and the HashiCorp ecosystem. Infrastructure as code allows users to define and provision infrastructure through code rather than manual configuration. It can be used to launch, create, change, and downscale infrastructure based on configuration files. Tools like Terraform allow showing what changes will occur before applying them through files like main.tf and variables.tf. Terraform is part of the broader HashiCorp ecosystem of tools.
Terraform
Terraform is an open source tool for building, changing, and versioning infrastructure safely and efficiently. It allows users to define and provision a datacenter infrastructure using a high-level configuration language known as HashiCorp Configuration Language. Some key features of Terraform include supporting multiple cloud providers and services, being declarative and reproducible, and maintaining infrastructure as code with immutable infrastructure. It works by defining configuration files that specify what resources need to be created. The configuration is written in HCL. Terraform uses these files to create and manage infrastructure resources like VMs, network, storage, containers and more across multiple cloud platforms.
Best Practices of Infrastructure as Code with Terraform
When your organization is moving to cloud, the infrastructure layer transitions from running dedicated servers at limited scale to a dynamic environment, where you can easily adjust to growing demand by spinning up thousands of servers and scaling them down when not in use.
The future of DevOps is infrastructure as code. Infrastructure as code supports the growth of infrastructure and provisioning requests. It treats infrastructure as software: code that can be re-used, tested, automated and version controlled. HashiCorp Terraform adopts infrastructure as code throughout its tool to prevent configuration drift, manage immutable infrastructure and much more!
Join this webinar to learn why Infrastructure as Code is the answer to managing large scale, distributed systems and service-oriented architectures. We will cover key use cases, a demo of how to use Infrastructure as Code to provision your infrastructure and more:

A Hands-on Introduction on Terraform Best Concepts and Best Practices
At our OC DevOps Meetup, we invited Rami Al-Ghami, a Sr. Software engineer at Workday to deliver a presentation on a Hands-On Terraform Best Concepts and Best Practices.
The software lifecycle does not end when the developer packages their code and makes it ready for deployment. The delivery of this code is an integral part of shipping a product. Infrastructure orchestration and resource configuration should follow a similar lifecycle (and process) to that of the software delivered on it. In this talk, Rami will discuss how to use Terraform to automate your infrastructure and software delivery.

Troubleshooting Kerberos in Hadoop: Taming the Beast
Kerberos is the ubiquitous authentication mechanism when it comes to secure any Hadoop Services. With recent updates in Hadoop core and various Apache Hadoop components, inherent Kerberos support has matured and has come a long way.
Understanding & configuring Kerberos is still a challenge but even more painful & frustrating is troubleshooting a Kerberos issue. There are lot of things (small & big) that can go wrong (and will go wrong!). This talk covers the Kerberos debugging part in detail and discusses the tools & tricks that can be used to narrow down any Kerberos issue.
Rather than discussing the issues and their resolution, we will focus on how to approach a Kerberos problem and do's / dont's in Kerberos scene. This talk will provide a step by step guide that will equip the audience for troubleshooting future Kerberos problems.
Agenda is to discuss:
- Systematic approach to Kerberos troubleshooting
- Kerberos Tools available in Hadoop arsenal
- Tips & Tricks to narrow down Kerberos issues quickly
- Some nasty Kerberos issues from Support trenches
Some prior knowledge on Kerberos basics will be appreciated but is not a prerequisite.

Real time cloud native open source streaming of any data to apache solr
Real time cloud native open source streaming of any data to apache solr
Utilizing Apache Pulsar and Apache NiFi we can parse any document in real-time at scale. We receive a lot of documents via cloud storage, email, social channels and internal document stores. We want to make all the content and metadata to Apache Solr for categorization, full text search, optimization and combination with other datastores. We will not only stream documents, but all REST feeds, logs and IoT data. Once data is produced to Pulsar topics it can instantly be ingested to Solr through Pulsar Solr Sink.
Utilizing a number of open source tools, we have created a real-time scalable any document parsing data flow. We use Apache Tika for Document Processing with real-time language detection, natural language processing with Apache OpenNLP, Sentiment Analysis with Stanford CoreNLP, Spacy and TextBlob. We will walk everyone through creating an open source flow of documents utilizing Apache NiFi as our integration engine. We can convert PDF, Excel and Word to HTML and/or text. We can also extract the text to apply sentiment analysis and NLP categorization to generate additional metadata about our documents. We also will extract and parse images that if they contain text we can extract with TensorFlow and Tesseract.
Apache NiFi in the Hadoop Ecosystem
The document discusses Apache NiFi and its role in the Hadoop ecosystem. It provides an overview of NiFi, describes how it can be used to integrate with Hadoop components like HDFS, HBase, and Kafka. It also discusses how NiFi supports stream processing integrations and outlines some use cases. The document concludes by discussing future work, including improving NiFi's high availability, multi-tenancy, and expanding its ecosystem integrations.

It provides an overview of Cloudera Search's architecture and components, which integrate Apache Solr with Cloudera Distribution of Hadoop to enable distributed, full-text search across data stored in HDFS. Key components described include HDFSDirectory, which allows Solr to read and write indexes and transaction logs to and from HDFS, and BlockDirectoryCache, which caches index file blocks in memory for performance.
Is your Enterprise Data lake Metadata Driven AND Secure?
This document discusses how Apache Atlas and Apache Ranger can be used together to provide a metadata-driven and secure data lake. Apache Atlas provides metadata services and tagging capabilities. Apache Ranger uses the tags in Atlas to dynamically define and enforce access policies. The integration allows Ranger policies to automatically apply and change as Atlas metadata such as tags are updated. The document demonstrates how tags in Atlas for columns and tables can be used to create time-based and PII data access policies in Ranger.
Classification based security in Hadoop
The Atlas/ Ranger integration represents a paradigm shift for big data governance and security. Enterprises can now implement dynamic classification-based security policies, in addition to role-based security. Ranger’s centralized platform empowers data administrators to define security policy based on Atlas metadata tags or attributes and apply this policy in real-time to the entire hierarchy of data assets including databases, tables and columns.
