Subject [jira] Commented: (HADOOP-1274) Configuring different number of mappers and reducers per TaskTracker
Date Thu, 19 Apr 2007 23:38:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12490198
] 

Michael Bieniosek commented on HADOOP-1274:
-------------------------------------------

See my HADOOP-1245.  Currently this is possible by setting mapred.tasktracker.tasks.maximum
differently for tasktrackers, but the jobtracker will  assign an inappropriate number of jobs
when it initially creates the job.

assigned to each node.
