Review request for hive and John Sichi.


Address comments, add TestNegativeMinimrCliDriver testcase to cover negative testcases.


- Add local error messages to point to job logs and provide TaskIDs
- Add a timeout to the fetching of task logs and errors

This addresses bug HIVE-2156.

>             Project: Hive
>          Issue Type: Improvement
>            Reporter: Syed S. Albiz

>         Attachments: HIVE-2156.1.patch, HIVE-2156.2.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;
