> Project: Hive
> Issue Type: Improvement
> Affects Versions: 0.8.0
> Reporter: Kathleen Ting
>
> Got opaque error message FAILED: Execution Error, return code 2 from
> org.apache.hadoop.hive.ql.exec.MapRedTask which tedious trial and error
> deduced to be an MR misconfiguration on io.sort.mb, namely the map buffer
> size was too small for the allocated child heap size.
> Would be helpful if the error message was more specific.
