Subject [jira] [Commented] (MAPREDUCE-3315) Master-Worker Application on YARN
Date Wed, 04 Apr 2012 19:13:18 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13246609#comment-13246609

Robert Joseph Evans commented on MAPREDUCE-3315:
------------------------------------------------

If you pass in a port number of 0 the OS will pick a free port.  You can then query the server
to know what port it actually bound to.

> Currently master worker scenarios are forced fit into Map-Reduce. Now with YARN, these
can be first class and would benefit real/near realtime workloads and be more effective in
using the cluster resources.
