> datanodesSoftwareVersions map may counting wrong when rolling upgrade
> ---------------------------------------------------------------------
>
> Key: HDFS-9500
> URL: https://issues.apache.org/jira/browse/HDFS-9500
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.7.1, 2.6.2
> Reporter: Phil Yang
> Assignee: Erik Krogen
> Attachments: 9500-v1.patch, HDFS-9500.000.patch
>
>
> While rolling upgrading, namenode's website overview will report there are
> two versions datanodes in the cluster, for example, 2.6.0 has x nodes and
> 2.6.2 has y nodes. However, sometimes when I stop a datanode in old version
> and start a new version one, namenode only increases the number of new
> version but not decreases the number of old version. So the total number x+y
> will be larger than the number of datanodes. Even all datanodes are upgraded,
> there will still have the messages that there are several datanode in old
> version. And I must run hdfs dfsadmin -refreshNodes to clear this message.
> I think this issue is caused by DatanodeManager.registerDatanode. If nodeS in
> old version is not alive because of shutting down, it will not pass
> shouldCountVersion, so the number of old version won't be decreased. But this
> method only judges the status of heartbeat and isAlive at that moment, if
> namenode has not removed this node which will decrease the version map and
> this node restarts in the new version, the decrementVersionCount belongs to
> this node will never be executed.
> So the simplest way to fix this is that we always recounting the version map
> in registerDatanode since it is not a heavy operation.
