> Follow-up to HIVE-1731
> A number of issues were related to reporting errors from task execution and surfacing these in a more useful form.
> Currently a cryptic message with "Execution Error" and a return code and class name of the task is emitted.
> The most useful log messages here are emitted to the local logs, which can be found through jobtracker. Having either a pointer to these logs as part of the error message or the actual content would improve the usefulness substantially. It may also warrant looking into how the underlying error reporting through Hadoop is done and if more information can be propagated up from there.
> Specific issues raised in  HIVE-1731:
> FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.MapRedTask
> * issue was in regexp_extract syntax
> FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
> * tried: desc table_does_not_exist;
