Nigel Daley commented on MAPREDUCE-2285: ---------------------------------------- Yes Todd, please commit to trunk and 0.22. Thanks! > MiniMRCluster does not start after ant test-patch > ------------------------------------------------- > > Key: MAPREDUCE-2285 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2285 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: test > Reporter: Ramkumar Vadali > Priority: Blocker > Fix For: 0.22.0, 0.23.0 > > Attachments: cp-bad, cp-good, fix-build.diff > > > 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: > {code} > [junit] 11/01/27 12:11:43 INFO ipc.Server: IPC Server handler 3 on 58675: > starting > [junit] 11/01/27 12:11:43 INFO mapred.TaskTracker: TaskTracker up at: > localhost.localdomain/127.0.0.1:58675 > [junit] 11/01/27 12:11:43 INFO mapred.TaskTracker: Starting tracker > tracker_host0.foo.com:localhost.localdomain/127.0.0.1:58675 > [junit] 11/01/27 12:11:44 INFO ipc.Client: Retrying connect to server: > localhost/127.0.0.1:0.
