Santhosh Srinivasan updated PIG-158:
------------------------------------
Attachment: udf_fix.patch
The udf_fix.patch fixes the following:
1. The return type of udf was not being returned correctly (Thanks Shravan)
2. The mergeType in DataType was not merging BYTEARRAY properly (Thanks Shravan)
3. TypeCheckingVisitor was not checking for NULL schema in LOGenerate
4. Fixed test cases corresponding to the fix for the mergeType
5. The findType method in DataType now handles interfaces. Shravan added this.
I am submitting this as part of this patch.
TODO:
testDefinedFunctions fails in TestMapReduce.java. I also saw a parser error
when I changed the test case.
