Subject [jira] [Created] (MAPREDUCE-3920) Revise yarn default port number selection
Date Fri, 24 Feb 2012 21:47:48 GMT
Revise yarn default port number selection

                 Key: MAPREDUCE-3920
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3920
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: nodemanager, resourcemanager
    Affects Versions: 0.23.1
            Reporter: Dave Thompson
            Assignee: Dave Thompson
             Fix For: 0.23.1

The default port numbers chosen for nodemanager and resourcemanager are random and widely
spread out creating unnecessary overhead in deployments where site operators care, and deploy
many clusters.

Current and proposed new default ports are as follows:

Current		New		Config Property	
------- 	---             ---------------
4344		8040		yarn.nodemanager.localizer.address	
45454		8041		yarn.nodemanager.address	
9999		8042		yarn.nodemanager.webapp.address	

8030		8030(NC)	yarn.resourcemanager.scheduler.address
8025		8031		yarn.resourcemanager.resource-tracker.address
8040		8032		yarn.resourcemanager.address
8141		8033		yarn.resourcemanager.admin.address

Affected files include:  embedded defaults (YarnConfiguration.java), yarn-default.xml, documentation
and unit tests.
