Rushabh S Shah resolved HDFS-5773.
----------------------------------
Resolution: Not a Problem
> NN may reject formerly dead DNs
> -------------------------------
>
> Key: HDFS-5773
> URL: https://issues.apache.org/jira/browse/HDFS-5773
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.0.0-alpha, 3.0.0, 0.23.10
> Reporter: Daryn Sharp
> Assignee: Rushabh S Shah
> Priority: Critical
>
> If the heartbeat monitor declares a node dead, it may never allow a DN to
> rejoin. The NN will generate messages like "Got blockReceivedDeleted message
> from unregistered or dead node".
> There appears to be a bug where the the isAlive flag is not set to true when
> a formerly known DN attempts to rejoin.
