Subject [jira] [Updated] (HIVE-2156) Improve error messages emitted during task execution
Date Thu, 11 Aug 2011 01:07:27 GMT

     [ https://issues.apache.org/jira/browse/HIVE-2156?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Syed S. Albiz updated HIVE-2156:
--------------------------------

    Attachment: HIVE-2156.13.patch

The previous patch was failing as I generated it using '-Doverwrite=true', and minimr_broken_pipe.q
was being written over twice. I have fixed the patch to exclude minimr_broken_pipe.q from
the regular TestNegativeCliDriver test run, and also updated the diff ignores to prevent the
TestNegativeMinimrCliDriver failure

> 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;
