HWI: propagate error messages all the way up to user interface
--------------------------------------------------------------
Key: HIVE-822
URL: https://issues.apache.org/jira/browse/HIVE-822
Project: Hadoop Hive
Issue Type: New Feature
Components: Web UI
Affects Versions: 0.4.0
Reporter: Abhijit Pol
> I can see error code propagated in HWI. Is there a way to propagate error
> message all the way up to the user interface?
> Often user make an error entering query and they only get to know the error
> code (10 or 11). But they don't get any hint on how to fix it...
>
> Thanks,
> Abhi
Abhi,
>From memory the CLI handles that by sending the output to SessionState.err. We
>also might be able to collect the last exception and store it. We left a hook
>open to write the error stream to a separate file. Open up a Jira, and we can
>talk about the best way to implement it.
Thank you,
Edward
