Subject [jira] Created: (HDFS-615) TestLargeDirectoryDelete fails with NullPointerException
Date Sat, 12 Sep 2009 01:46:57 GMT
TestLargeDirectoryDelete fails with NullPointerException
--------------------------------------------------------

                 Key: HDFS-615
                 URL: https://issues.apache.org/jira/browse/HDFS-615
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.21.0
         Environment: 64-bit debian 5, 64-bit sun java6, running in a single processor VM.
            Reporter: Eli Collins
            Priority: Minor


I've hit the following failure two out of two times running "ant test" at rev 813587. This
test doesn't appear to be failing on hudson. All other tests passed except TestHDFSFileSystemContract
which timed out, so perhaps there's a race due to the test executing slowly. 

    [junit] Running org.apache.hadoop.hdfs.server.namenode.TestLargeDirectoryDelete

                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^  No failures or errors?

  public static FSNamesystem getNamesystem(NameNode namenode) {
    return namenode.getNamesystem();                                                     
     <===========
  }
