Subject [jira] [Updated] (MAPREDUCE-2400) Remove Cluster's dependency on JobTracker
Date Wed, 13 Jul 2011 03:35:00 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2400?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod Kumar Vavilapalli updated MAPREDUCE-2400:

    Attachment: MAPREDUCE-2400-bugfix-20110713.txt

Here's a small patch to fix minor bugs and error reporting.
 - Fixes JobTrackerClientProtocolProvider to use the configs to return a correct provider
when  _create(InetSocketAddress addr, Configuration conf)_ is called. Same for LocalClientProtocolProvider.
Also fixed both to report better when misconfigured.
 - It also removes the numMaps set to 1 for LocalJobRunner, we don't need this.

I tested the committed-patch with this bug-fix on a single node secure setup, things are good.

Arun/Tom, can you please take a look. Thanks!
