Colin Patrick McCabe commented on HDFS-7719:
--------------------------------------------
I ran TestDFSMkdirs locally and can confirm that it succeeds. This is
definitely Jenkins flakiness. Committed to 2.7
> BlockPoolSliceStorage#removeVolumes fails to remove some in-memory state

> Key: HDFS-7719
> URL: https://issues.apache.org/jira/browse/HDFS-7719
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.6.0
> Reporter: Lei (Eddy) Xu
> Assignee: Lei (Eddy) Xu

>
> The parameter of {{BlockPoolSliceStorage#removeVolumes()}} is a set of volume
> level directories, thus {{BlockPoolSliceStorage}} could not directly compare
> its own {{StorageDirs}} with this volume-level directory. The result of that
> is {{BlockPoolSliceStorage}} did not actually remove the targeted
> {{StorageDirectory}}.
> It will cause failure when remove a volume and then immediately add a volume
> back with the same mount point..
