Optimize build.xml
------------------
Key: PIG-654
URL: https://issues.apache.org/jira/browse/PIG-654
Project: Pig
Issue Type: Improvement
Components: impl
Affects Versions: types_branch
Reporter: Daniel Dai
Assignee: Daniel Dai
Priority: Trivial
Fix For: types_branch
Build process can be faster. Here is the issues slow down the build process:
1. Should change test/org/apache/pig/test/utils/dotGraph/Dot.jjt to
DOTParser.jjt. [jjtree] assumes the output file name the same with the input
file name, otherwise, it will recompile every time
2. Delete
src/org/apache/pig/backend/hadoop/executionengine/physicalLayer/relationalOperators/POPostCombinerPackage.java
and src/org/apache/pig/impl/plan/SplitIntroducer.java, both classes are empty
and generates no class file. Ant will recompile them every time since it do not
see the output class file.
I do not know how to create a patch with file deletion and rename, so I
describe the actions below:
1. mv test/org/apache/pig/test/utils/dotGraph/Dot.jjt
test/org/apache/pig/test/utils/dotGraph/DOTParser.jjt
2. rm
src/org/apache/pig/backend/hadoop/executionengine/physicalLayer/relationalOperators/POPostCombinerPackage.java
3. rm src/org/apache/pig/impl/plan/SplitIntroducer.java
4. apply patch to change build.xml (Dot.jjt -> DOTParser.jjt)
