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.
> Rework logical plan
