[jira] Commented: (MAPREDUCE-2285) MiniMRCluster does not start
after ant test-patch
[ https://issues.apache.org/jira/browse/MAPREDUCE-2285?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12990481#comment-12990481 ]
Todd Lipcon commented on MAPREDUCE-2285:
----------------------------------------
This problem also causes failures in compiling mrunit's tests. eg this build: https://hudson.apache.org/hudson/job/Hadoop-Mapreduce-22-branch/25/
(failed with weird errors about assert methods not existing in junit)
The patch I attached last week fixes it. Giri: was your "looks good" a +1? (ie can I commit to branch and trunk?)

> Any test using MiniMRCluster hangs in the MiniMRCluster constructor after running ant test-patch. Steps to reproduce:
> 1. ant -Dpatch.file=<dummy patch to CHANGES.txt> -Dforrest.home=<path to forrest> -Dfindbugs.home=<path to findbugs> -Dscratch.dir=/tmp/testpatch -Djava5.home=<path to java5> test-patch
> 2. Run any test that creates MiniMRCluster, say ant test -Dtestcase=TestFileArgs (contrib/streaming)
> Expected result: Test should succeed
> Actual result: Test hangs in MiniMRCluster.<init>. This does not happen if we run ant clean after ant test-patch
> Test output:
