Subject [jira] Commented: (MAPREDUCE-2213) [Gridmix] Gridmix doesnt work with LocalJobRunner
Date Wed, 08 Dec 2010 06:35:00 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12969205#action_12969205
] 

Amar Kamat commented on MAPREDUCE-2213:
---------------------------------------

There are 2 issues 
-  Gridmix's GenerateData job uses the number of tracker available in the cluster to distribute
the data generation. LocalJobRunner returns *null* for _getActiveTrackers()_ and _getBlacklistedTrackers()_.

- The exceptions are eaten up by GridMix thus making it tough to debug.
