Subject [jira] [Created] (HDFS-4768) block scanner does not close verification log when a block pool is being deleted (but the datanode remains running)
Date Fri, 26 Apr 2013 22:08:16 GMT
Chris Nauroth created HDFS-4768:
-----------------------------------

             Summary: block scanner does not close verification log when a block pool is being
deleted (but the datanode remains running)
                 Key: HDFS-4768
                 URL: https://issues.apache.org/jira/browse/HDFS-4768
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
    Affects Versions: 3.0.0, 2.0.4-alpha
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


HDFS-4274 fixed a file handle leak of the block scanner's verification logs by adding method
{{BlockPoolSliceScanner#shutdown}} and guaranteeing that the method gets called for each live
{{BlockPoolSliceScanner}} during datanode shutdown.  However, that patch did not consider
the case of deleting a block pool via {{ClientDatanodeProtocol#deleteBlockPool}} while the
datanode remains running.
