Matteo Bertozzi commented on HBASE-8116:
----------------------------------------
I thought that this test was removed before merge,
it has too many assumption and it is bounded to fail
also it doesn't really test nothing new in respect of the already present, and
more accurate TestRestoreSnapshot or TestFlushSnapshot..
> TestSnapshotCloneIndependence fails in trunk builds intermittently
