[jira] Commented: (HADOOP-5945) Support running multiple DataNodes/TaskTrackers simultaneously in a single node

["Jakob Homan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-5945?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12714746#action_12714746 ] 

Jakob Homan commented on HADOOP-5945:
-------------------------------------

It's possible now to run multiple datanodes/tasktrackers on the same node, simply by writing separate configuration files for each.  I do it quite often during testing.  There is some limited discussion on the mailing lists for how to do this, but there certainly could be a more concise, step-by-set set of instructions.  Are you meaning to do this on production machines?

> 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.
