Subject [jira] Commented: (HADOOP-5945) Support running multiple DataNodes/TaskTrackers simultaneously in a single node
Date Tue, 02 Jun 2009 13:08:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12715519#action_12715519

Steve Loughran commented on HADOOP-5945:
----------------------------------------

The big issue is what do you gain by running >1 TT and DN per node, except on testing,
where you want to give the master nodes more of a workload?

> We should support multiple datanodes/tasktrackers running at a same node, only if they
do not share same port/local fs dir etc. I think Hadoop can be easily adapted to meet this.
 
> I guess at first and the major step is that we should modify the script to let it support
startting multiple datanode/tasktracker daemons in a same node.
