Subject [jira] [Created] (HDFS-4833) Corrupt blocks are not invalidated when first processing repl queues
Date Thu, 16 May 2013 20:59:16 GMT
Todd Lipcon created HDFS-4833:
---------------------------------

             Summary: Corrupt blocks are not invalidated when first processing repl queues
                 Key: HDFS-4833
                 URL: https://issues.apache.org/jira/browse/HDFS-4833
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.0.4-alpha
            Reporter: Todd Lipcon


When the NN processes misreplicated blocks in {{processMisReplicatedBlock}} (eg during initial
startup when first processing repl queues), it does not invalidate corrupt replicas unless
the block is also over-replicated. This can result in replicas stuck in "corrupt" state forever
if they were that way when the cluster booted.
