Subject [jira] Updated: (PIG-158) Rework logical plan
Date Thu, 29 May 2008 14:40:44 GMT

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

Santhosh Srinivasan updated PIG-158:
------------------------------------

    Attachment: udf_return_type.patch

The udf_return_type.patch fixes the following issues:

1. The return type of UDF is deduced (Thanks Shravan)
2. The logical plan for store was not returned appropriately. Thats fixed now (Thanks Shravan)
3. Shravan fixed an issue with the Logical to Physical translator. I have included that fix
as part of this patch.
4. Changed PigServer to use logical plans for executing instead of looking up the logical
plan through aliases.

TODO:

1. A couple of map reduce unit test cases are failing.
2. Integrate pigRegisterFunction with the Parser
3. Fix an issue with getFieldSchema() method in LOProject.
