> When a volume fails in datanode, the call to {{VersionEndpointTask#call}}
> ends up in dead-lock.
> {code:java}
> org.apache.hadoop.ozone.container.common.states.endpoint.VersionEndpointTask.call(VersionEndpointTask.java:78)
> --> we acquire VolumeSet read lock here.
> org.apache.hadoop.ozone.container.common.states.endpoint.VersionEndpointTask.call(VersionEndpointTask.java:93)

> org.apache.hadoop.ozone.container.common.volume.VolumeSet.failVolume(VolumeSet.java:276)
>
> org.apache.hadoop.ozone.container.common.volume.VolumeSet.writeLock(VolumeSet.java:210)
> ---> we wait for VolumeSet write lock.
> {code}
> Since this thread already holds the read lock, it cannot get the write lock
> and ends up in dead-lock.
