Todd Lipcon updated HDFS-4833:
------------------------------
Affects Version/s: 1.2.0
> 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: 1.2.0, 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.
