DataNodes get NullPointerException and become unresponsive on 50010
-------------------------------------------------------------------

                 Key: HADOOP-604
                 URL: http://issues.apache.org/jira/browse/HADOOP-604
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.6.0
            Reporter: Christian Kunz


I wonder whether handling of 'children' in FSDataset is thread-safe.

Exception in thread "org.apache.hadoop.dfs.DataNode$DataXceiveServer@19b04e2" java.lang.NullPointerException
