Santhosh Srinivasan updated PIG-158:
------------------------------------
Attachment: parser_changes_v4.patch
Patch v4 that has the parser changes with the nested plans. The only test
cases that fail are that of instantiateFunc.
[junit] Running org.apache.pig.test.TestLogicalPlanBuilder
[junit] Tests run: 55, Failures: 9, Errors: 0, Time elapsed: 0.278 sec
Things to note:
1. LOUnion does not implement the method getSchema().
2. The flatten as alias feature introduces superfluous aliases in the
LOGenerate schema
3. I had to make changes to the type checking code and test cases in order to
compile
4. I commented out PigServer references in TestLogicalPlanBuilder.java as the
compiler complained that it could not find PigServer.java for some reason
> Rework logical plan
