["Santhosh Srinivasan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-398?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Santhosh Srinivasan updated PIG-398:
------------------------------------

    Attachment: Pig-398.patch

Patch, Pig-398.patch fixes the following:

1. Expression assignment within foreach is now re-instated
2. Visit methods for operators that contain nested plans in LOVisitor are fixed. Previously only the roots of the nested plans were visited.
3. Cast field schemas will no longer be reset during optimization
4. History will now persist across multiple pig interactive sessions - thanks to Raghotham S Murthy from Facebook.

Unit tests that still fail are:

    [junit] Running org.apache.pig.test.TestBuiltin
    [junit] Tests run: 23, Failures: 1, Errors: 2, Time elapsed: 14.363 sec
