Status: Patch Available (was: Open)
> MIN/MAX builtin UDFs return wrong results when accumulating for strings
> -----------------------------------------------------------------------
>
> Key: PIG-4490
> URL: https://issues.apache.org/jira/browse/PIG-4490
> Project: Pig
> Issue Type: Bug
> Components: internal-udfs
> Affects Versions: 0.12.0, 0.13.0, 0.14.0
> Reporter: xplenty
>
> When using MIN/MAX UDFs with strings in a job that uses the accumulator interface the results are wrong - The UDF won't return the correct MIN/MAX value.
> this is caused by a reverse 'GreaterThan/SmallerThan" (<>) sign in the accumulate() function of both StringMin/StringMax UDFs.
