> 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.
