Hortonworks - Hadoop 2.0: Developing Applications with HDP using Java (1HW-DAHJ)

Categories: Hadoop » Hadoop » Hadoop » Course 1HW-DAHJ

This advanced four-day course provides Java programmers a deep-dive into Hadoop 2.0 application development. Students will learn how to design and develop efficient and effective MapReduce applications for Hadoop 2.0 using the Hortonworks Data Platform. Students who attend this course will learn how to harness the power of Hadoop 2.0 to manipulate, analyze and perform computations on their Big Data. After successfully completing this training course each student will receive one free voucher for the Hortonworks Certified Apache Hadoop 2.x Java Developer exam.

Skills Gained

At the completion of the course students will be able to: Explain Hadoop 2.0 and the Hadoop Distributed File System Explain the new YARN framework in Hadoop 2.0 Develop a Java MapReduce application Run a MapReduce application on YARN Use combiners and in-map aggregation to improve the performance of a MapReduce job Write a custom partitioner to avoid data skew on reducers Perform a secondary sort by writing custom key and group comparator classes Recognize use cases for the various built-in input and output formats Write a custom input and output format for a MapReduce job. Optimize a MapReduce job by following best practices Configure various aspects of a MapReduce job to optimize mappers and reducers Develop a custom RawComparator class Use the Distributed Cache Explain the various join techniques in Hadoop Perform a map-side join Use a Bloom filter to join two large datasets Perform unit tests using the UnitMR API Explain the basic architecture of HBase Write an HBase MapReduce application Explain use cases for Pig and Hive Write a simple Pig script to explore and transform big data Write a Pig UDF (User-Defined Function) in Java Execute a Hive query Write a Hive UDF in Java Use the JobControl class to create a workflow of MapReduce jobs Use Oozie to define and schedule workflows

Who Can Benefit

Experienced Java software engineers who need to understand and develop Java MapReduce applications for Hadoop 2.0.

Prerequisites

This course assumes students have experience developing Java applications and using a Java IDE. Labs are completed using the Eclipse IDE and Maven. No prior Hadoop knowledge is required.
