Subject [jira] [Commented] (MAPREDUCE-4406) Users should be able to specify the MiniCluster ResourceManager and JobHistoryServer ports
Date Fri, 13 Jul 2012 23:20:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13414139#comment-13414139

Alejandro Abdelnur commented on MAPREDUCE-4406:

The first patch would reintroduce fixed ports in the minicluster, we don't want that for running

We could achieve this by having a new config property, ie 'hadoop.minicluster.fixed.ports'
= FALSE (default).

If this property is FALSE, we use the current random port configuration.

If this property is TRUE, we use the fixed port behavior from configuration.

Then MAPREDUCE-987 would set this property to TRUE before starting the minicluster.

This wouldn't change the current random behavior which is desirable for dev/jenkins.

> There is use-cases where users may need to specify the ports used for the resource manager
and history server for the minicluster.
> In the current implementation, the MiniCluster sets these addresses regardless of them
being already set by the user in the conf.
> Users should be able to add these properties to the conf and in such case the MiniCluster
will use the specified addresses. If not specified then the current behavior of the MiniCluster
for explicitly setting the addresses will be used.
> I'll be uploading a patch momentarily.
