Subject [jira] [Created] (HDFS-5558) LeaseManager monitor thread can crash if the last block is complete but another block is not.
Date Sat, 23 Nov 2013 02:05:38 GMT
Kihwal Lee created HDFS-5558:
--------------------------------

             Summary: LeaseManager monitor thread can crash if the last block is complete
but another block is not.
                 Key: HDFS-5558
                 URL: https://issues.apache.org/jira/browse/HDFS-5558
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Kihwal Lee


As mentioned in HDFS-5557, a file has its last and penultimate block not completed and the
file is being closed, the last block can be completed but the penultimate one might not. If
this condition lasts long and the file is abandoned, LeaseManager will try to recover the
lease and the block. But {{ internalReleaseLease}} will fail with invalid cast exception with
this kind of file.
