Subject [jira] Updated: (PIG-158) Rework logical plan
Date Wed, 07 May 2008 06:53:55 GMT

     [ https://issues.apache.org/jira/browse/PIG-158?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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
