             Summary: ToString(datetime [, format string]) doesn't work without the second argument
                 Key: PIG-3805
                 URL: https://issues.apache.org/jira/browse/PIG-3805
             Project: Pig
          Issue Type: Bug
          Components: internal-udfs
    Affects Versions: 0.12.0
            Reporter: Jenny Thompson
            Priority: Minor


The exec function of ToString is written to handle a 1 or 2 arguments (it defaults to ISO, which is consistent with ToDate).

However, the getArgToFuncMapping function returns only one FuncSpec, requiring the formatString argument.

To fix: just return add another FuncSpec to getArcToFuncMapping.
