Subject [jira] [Commented] (HIVE-3376) Local mode errors point to the wrong file
Date Mon, 13 Aug 2012 17:20:37 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13433325#comment-13433325
] 

Gang Tim Liu commented on HIVE-3376:
------------------------------------

While executing in local mode, the process to collect failed job information is a different
process from running local MR job. Each process reads a different log4j property file. One
points to hive.log and another is MR job log.
No communication on 2 processes yet on job log. There are some ways like external files etc.
Consider the bug impact itself (log file location), easy way is to pass MR job stream and
pick up log file location and output in CLI stream.

> This is a classic example of a query that fails due to a bad udf in local mode:
> Ended Job = job_local_0001 with errors
> Error during job, obtaining debugging information...
> Execution failed with exit status: 2
> Obtaining error information
> Task failed!
> Task ID:
> Stage-1
> Logs:
> /tmp/gang/hive.log
> FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.MapRedTask
> But actually local mr job in /tmp/gang/gang_20120808181010_b716b5fb-5b8f-49d2-94e9-95bb8f465342.log
