Ning Zhang commented on HIVE-2156:
----------------------------------
Syed, there are still 2 tests failing: minimr_broken_pipe.q in
TestNegativeCliDriver and TestNegativeMinimrCliDriver. Can you take yet another
look? Also please rerun all unit tests and make sure all of them pass before
submitting. Otherwise it takes too many iterations.
> Improve error messages emitted during task execution

> Key: HIVE-2156
> URL: https://issues.apache.org/jira/browse/HIVE-2156
> Project: Hive
> Issue Type: Improvement
> Reporter: Syed S. Albiz
> Assignee: Syed S. Albiz
> Attachments: HIVE-2156.1.patch, HIVE-2156.10.patch,
> HIVE-2156.11.patch, HIVE-2156.12.patch, HIVE-2156.2.patch, HIVE-2156.4.patch,

>
> 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;
