[jira] [Commented] (MAPREDUCE-5036) Default shuffle handler port should not be 8080

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5036?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13588750#comment-13588750 ] 

Robert Joseph Evans commented on MAPREDUCE-5036:
------------------------------------------------

Technically the shuffle handler is a web service. If you want to change the default port I am fine with that, I am just curious what other web services do you expect to have running on the same node?

> The shuffle handler port defaults to 8080.  This is a pretty common port for web services, and is likely to cause unnecessary port conflicts.
