Objectives – Upon completing this Module, you should be able to understand Hive is a system for managing and querying unstructured data into a structured format.
The various components of Hive architecture are metastore, driver, execution engine, and so on
Metastore is a component that stores the system catalog and metadata about tables, columns, partitions, and so on
Hive installation starts with locating the latest version of tar file and downloading it in Ubuntu system using the wget command
While programming in Hive, use the show tables command to display the total number of tables
Topics:Introduction to Hive & features

- Types of hive tables flow
- DML/DDL commands explanation
- Partitioning logic
- Bucketing logic
- Hive script execution in shell & HUE
Module 4 – Apache Pig Duration :03:00:00
Goal : In this module, you will learn Pig, types of use case we can use Pig, tight coupling between Pig and MapReduce, and Pig Latin scripting, PIG running modes, PIG UDF, Pig Streaming, Testing PIG Scripts. Demo on healthcare dataset.
Objectives – Upon completing this Module, you should be able to understand Pig is a high-level data flow scripting language and has two major components: Runtime engine and Pig Latin language.
Pig runs in two execution modes: Local mode and MapReduce mode. Pig script can be written in two modes: Interactive mode and Batch mode.
Pig engine can be installed by downloading the mirror web link from the website: pig.apache.org.
- Introduction to Pig concepts
- Pig modes of execution/storage concepts
- Pig program logics explanation
- Pig basic commands
- Pig script execution in shell/HUE
Module 5 Duration :03:00:00
Goal : This module will cover Advanced HBase concepts. We will see demos on Bulk Loading, Filters. You will also learn what Zookeeper is all about, how it helps in monitoring a cluster, why HBase uses Zookeeper.
Objectives – Upon completing this Module, you should be able to understand HBasehas two types of Nodes—Master and RegionServer. Only one Master node runs at a time. But there can be multiple RegionServersat a time.
The data model of Hbasecomprises tables that are sorted by rows. The column families should be defined at the time of table creation.
There are eight steps that should be followed for installation of HBase.
Some of the commands related to HBaseshell are create, drop, list, count, get, and scan.
- Apache Hbase
- Introduction to Hbase concepts
- Introdcution to NoSQL/CAP theorem concepts
- Hbase design/architecture flow
- Hbase table commands
- Hive + Hbase integration module/jars deployment
- Hbase execution in shell/HUE
Module 6 Duration :02:00:00
Goal : Sqoop is an Apache Hadoop Eco-system project whose responsibility is to import or export operations across relational databases. Some reasons to use Sqoop are as follows:
- SQL servers are deployed worldwide
- Nightly processing is done on SQL servers
- Allows to move certain part of data from traditional SQL DB to Hadoop
- Transferring data using script is inefficient and time-consuming
- To handle large data through Ecosystem
- To bring processed data from Hadoop to the applications
Sqoop allows the import data from an RDB, such as SQL, MySQL or Oracle into HDFS.
- Apache Sqoop
- Introduction to Sqoop concepts
- Sqoop internal design/architecture
- Sqoop Import statements concepts
- Sqoop Export Statements concepts
- Quest Data connectors flow
- Incremental updating concepts
- Creating a database in MySQL for importing to HDFS
- Sqoop commands execution in shell/HUE
Module 7 Duration :02:00:00
Goal : Apache Flume is a distributed data collection service that gets the flow of data from their source and aggregates them to where they need to be processed.
Objectives – Upon completing this Module, you should be able to understand Apache Flume is a distributed data collection service that gets the flow of data from their source and aggregates the data to sink.
Flume provides a reliable and scalable agent mode to ingest data into HDFS.
- Apache Flume
- Introduction to Flume & features
- Flume topology & core concepts
- Property file parameters logic
Module 8 Duration :02:00:00
Goal : Hue is a web front end offered by the ClouderaVM to Apache Hadoop.
Objectives – Upon completing this Module, you should be able to understand how to use hue for hive,pig,oozie.
- Apache HUE
- Introduction to Hue design
- Hue architecture flow/UI interface
Module 9 Duration :02:00:00
Goal : Following are the goals of ZooKeeper:
- Serialization ensures avoidance of delay in reading or write operations.
- Reliability persists when an update is applied by a user in the cluster.
- Atomicity does not allow partial results. Any user update can either succeed or fail.
- Simple Application Programming Interface or API provides an interface for development and implementation.
Objectives – Upon completing this Module, you should be able to understand ZooKeeper provides a simple and high-performance kernel for building more complex clients.
- Apache Zookeeper
- Introduction to zookeeper concepts
- Zookeeper principles & usage in Hadoop framework
- Basics of Zookeeper
ZooKeeper has three basic entities—Leader, Follower, and Observer.
Watch is used to get the notification of all followers and observers to the leaders.
Module 10 Duration :05:00:00
Explain different configurations of the Hadoop cluster
Identify different parameters for performance monitoring and performance tuning
Explain configuration of security parameters in Hadoop.
Objectives – Upon completing this Module, you should be able to understand Hadoop can be optimized based on the infrastructure and available resources.
Hadoop is an open-source application and the support provided for complicated optimization is less.
Optimization is performed through xml files.
Logs are the best medium through which an administrator can understand a problem and troubleshoot it accordingly.
Hadoop relies on the Kerberos based security mechanism.
