Jenny Thompson updated PIG-3805:
--------------------------------
Status: Patch Available (was: Open)
> 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
> Labels: easyfix
> Attachments: PIG-3805.patch
>
>
> The exec function of ToString is written to handle 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.
