Description

In our cluster, we have a feature: take a snapshot when delete a table.

But when we restore the snapshot, we found that some data files are deleted.

The problem is that, when delete a table with merge regions, HBase only archive regions in meta, and merged parent regions are deleted in file system which contain data files in snapshot .
