Subject [jira] [Commented] (HADOOP-8089) cannot submit job from Eclipse plugin running on Windows
Date Sat, 18 Feb 2012 18:17:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13211041#comment-13211041

Weili Shao commented on HADOOP-8089:

I think I found the reason at high level, after I put a return to avoid that permission setting,
the job started with a localjobrunner and the result was written to the remote hdfs, which
confused me for a while, since I had no knowledge of localjobrunner before. Now I realize
that it's really that the JobClient wasn't initiated properly from the plugin xml conf, so
without any mapred.job.tracker settings, it just started the localjobrunner. After I added
the code:
    Configuration conf = new Configuration();
    conf.set("mapred.job.tracker", "[server]:9001");

It's working now. However. This configuration should be loaded from plugin's server configuration
and it used to be working.
