[jira] [Created] (PIG-4490) MIN/MAX builtin UDFs return wrong results when accumulating for strings

xplenty created PIG-4490:
----------------------------

             Summary: 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.
