Enis Soztutar resolved HBASE-11100.
-----------------------------------
Resolution: Duplicate
Let me resolve this as duplicate of HBASE-9445. I'll provide an updated patch
there. Thanks Vandana for reporting this.

> The integration test internally uses HBaseTestingUtility's loadtable API to
> create and load data into the regions. But that API does not seem to generate
> enough data for 32 regions ( which is the default number of regions in the
> integration test). As a result some regions end up with no keys. When the
> SnapshotTestingUtils calls confirmSnapshotValid method to verify the snaphot
> process, it looks for store files. When some region are empty they are not
> counted and hence the test fails.
