processMisReplicatedBlock incorrectly identifies under-construction blocks as
under-replicated
----------------------------------------------------------------------------------------------
Key: HDFS-2822
URL: https://issues.apache.org/jira/browse/HDFS-2822
Project: Hadoop HDFS
Issue Type: Bug
Components: ha, name-node
Affects Versions: 0.23.0, 0.24.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
When the NN processes mis-replicated blocks while exiting safemode, it
considers under-construction blocks as under-replicated, inserting them into
the neededReplicationsQueue. This makes them show up as corrupt in the metrics
and UI momentarily, until they're pulled off the queue. At that point, it
realizes that they aren't in fact under-replicated, correctly. This affects
both the HA branch and trunk/23, best I can tell.
