MiniMRCluster does not start after ant test-patch

      Description

      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:
