-----------------------------------

             Summary: AliasableEvalFunc should use getInputSchema
                 Key: DATAFU-25
                 URL: https://issues.apache.org/jira/browse/DATAFU-25
             Project: DataFu
          Issue Type: Improvement
            Reporter: Matthew Hayes


AliasableEvalFunc derives from ContextualEvalFunc and stores a map of aliases 
in the UDF context.  We can instead use getInputSchema, which was added to Pig 
0.11.  This may in the process resolve DATAFU-6.
