See
https://builds.apache.org/job/HBase-TRUNK/3901/testReport/org.apache.hadoop.hbase.client/TestSnapshotCloneIndependence/testOfflineSnapshotRegionOperationsIndependent/.
The root cause is that SnapshotManager does not invoke prepare() method for the
created CloneSnapshotHandler. Prepare has been introduced in HBASE-7305, and
acquires the table lock.
