Subject [jira] [Commented] (MAPREDUCE-2986) Multiple node managers support for the MiniYARNCluster
Date Wed, 26 Oct 2011 15:25:32 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2986?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13136037#comment-13136037
] 

Anupam Seth commented on MAPREDUCE-2986:
----------------------------------------

The javadoc warnings and Findbugs warnings are spurious and have nothing to do with my patch.

The unit test failures are not reproducible on my local machine even after many runs of the
test suite - I don't yet understand why it failed on Jenkins.

> The current MiniYARNCluster can only support 1 node manager, which is not enough for
the full test purposes.
> Would like to have a simulator that can support multiple node managers as the real scenario.
This might be beneficial for hadoop users, testers and developers.
