Pig
Recognize use cases for Pig, which include:
• ETL data pipelines
• Researching raw data
• Iterative data processing
Understand how Pig executes on a cluster:
• Pig runs on YARN as either a MapReduce
job or a Tez job.
• Pig reads and writes data from the Hadoop
Distributed File System (HDFS).
• The programming language for the Pig
platform is called Pig Latin, which allows
you to write a data flow that describes how
your data will be transformed and
processed (such as filtering, grouping,
joining and sorting data).
