Subject [jira] Commented: (HIVE-1776) parallel execution and auto-local mode combine to place plan file in wrong file system
Date Tue, 09 Nov 2010 23:40:23 GMT

    [ https://issues.apache.org/jira/browse/HIVE-1776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12930359#action_12930359

Ted Yu commented on HIVE-1776:
------------------------------

This line is removed from MapRedTask.java:

ctx.setOriginalTracker(conf.getVar(HiveConf.ConfVars.HADOOPJT));

I assume this is intentional.

> A query (that i can't reproduce verbatim) submits a job to a MR cluster with a plan file
that is resident on  the local file system. This job obviously fails.
> This seems to result from an interaction between the parallel execution (which is trying
to run one local and one remote job at the same time). Turning off either the parallel execution
mode or the auto-local mode seems to fix the problem.
