[jira] [Created] (HDFS-4867) metaSave NPEs when there are invalid blocks in repl queue.

Kihwal Lee created HDFS-4867:
--------------------------------

             Summary: metaSave NPEs when there are invalid blocks in repl queue.
                 Key: HDFS-4867
                 URL: https://issues.apache.org/jira/browse/HDFS-4867
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
    Affects Versions: 2.0.4-alpha, 0.23.7
            Reporter: Kihwal Lee


Since metaSave cannot get the inode holding a orphaned/invalid block, it NPEs and stops generating further report. Normally ReplicationMonitor removes them quickly, but if the queue is huge, it takes very long time. Also in safe mode, they stay.
