Hortonworks - HDP Developer: Apache Pig and Hive - Virtual (1HW-DPPH-VC)
This 4-day hands-on training course teaches students how to develop applications and analyze Big Data stored in Apache Hadoop 2.0 using Pig and Hive. Students will learn the details of Hadoop 2.0, YARN, the Hadoop Distributed File System (HDFS), an overview of MapReduce, and a deep dive into using Pig and Hive to perform data analytics on Big Data. Other topics covered include data ingestion using Sqoop and Flume, and defining workflow using Oozie. Note: this course was formerly named: Developing Apache Hadoop 2.0 Solutions for Data Analysts
Course Objectives At the completion of the course students will be able to: Explain Hadoop 2.0 and YARN Explain use cases for Hadoop Explain how HDFS Federation works in Hadoop 2.0 Explain the various tools and frameworks in the Hadoop 2.0 ecosystem Explain the architecture of the Hadoop Distributed File System (HDFS) Use the Hadoop client to input data into HDFS Use Sqoop to transfer data between Hadoop and a relational database Explain the architecture of MapReduce Explain the architecture of YARN Run a MapReduce job on YARN Write a Pig script to explore and transform data in HDFS Define advanced Pig relations Use Pig to apply structure to unstructured Big Data Invoke a Pig User-Defined Function Use Pig to organize and analyze Big Data Understand how Hive tables are defined and implemented Use the new Hive windowing functions Explain and use the various Hive file formats Create and populate a Hive table that uses the new ORC file format Use Hive to run SQL-like queries to perform data analysis Use Hive to join datasets using a variety of techniques, including Map-side joins and Sort-Merge-Bucket joins Write efficient Hive queries Create ngrams and context ngrams using Hive Perform data analytics like quantiles and page rank on Big Data using the DataFu Pig library Explain the uses and purpose of HCatalog Use HCatalog with Pig and Hive Define a workflow using Oozie Schedule a recurring workflow using the Oozie Coordinator
Who Can Benefit
Data Analysts, BI Analysts, BI Developers, SAS Developers and other types of analysts who need to answer questions and analyze Big Data stored in a Hadoop cluster.
Students should be familiar with programming principles and have experience in software development. SQL knowledge is also helpful. No prior Hadoop knowledge is required.
