Google Summer of Code 2015 for Pig

Pig is exciting! Pig provide an intuitive way to program hadoop. Inside Yahoo!, more than 80% of hadoop jobs are Pig jobs. It is heavily used in Twitter, Linkedin and lots of other organizations (https://cwiki.apache.org/confluence/display/PIG/PoweredBy).

This is the forth straight year Pig participate Google Summer of Code. Last year we accepted 5 students and 4 of them complete their projects successfully.

Here we picked up a list of highly desired projects for students. Once accepted, we will assign a dedicated mentor to guide you through different stages of the program. We need your help and you will get a great experience of participating an open source project.

Getting start

First, you need to learn PigLatin language. The best source for learning PigLatin is:

• Pig Latin Reference
• Pig Latin paper at SIGMOD 2008
• Pig Tutorial
• Pig optimizor paper

Be sure to sign up pig mailing list.

Then checkout Pig source code using svn:
svn co http://svn.apache.org/repos/asf/pig/trunk

Set up environment for Eclipse:https://cwiki.apache.org/confluence/display/PIG/How+to+set+up+Eclipse+environment

Learn more about Pig internal at Pig paper at VLDB 2009.

Browse through Pig code. Some good start points are:

• QueryLexer.g, QueryParser.g, LogicalPlanGenerator.g: Pig parser, LogicalPlan construction
• LogToPhyTranslationVisitor: From logical plan to physical plan
• MRCompiler: From physical plan to map-reduce plan
• JobControlCompiler: From map-reduce plan to hadoop job
• MapReduceLauncher: Hadoop launcher
• PigMapBase: map class for Pig
• PigMapReduce: reduce class for Pig

Try to start with something simpler: https://issues.apache.org/jira/browse/PIG-3371?jql=project%20%3D%20PIG%20AND%20resolution%20%3D%20Unresolved%20AND%20labels%20%3D%20newbie
