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

     [ https://issues.apache.org/jira/browse/PIG-380?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Santhosh Srinivasan updated PIG-380:
------------------------------------

    Attachment: PIG-380.patch

Attached patch (PIG-380.patch) addresses the following:

1. Computes the field schema of constants
2. Fixes issues in the type checker for bincond, mod and user function type checking
3. New unit tests and changes to existing unit tests to accommodate the schema computation of constants

Note: The schema of a bag constant will contain the schema of a tuple which in turn contains the columns.

All unit tests pass.
