Lars Hofhansl commented on HBASE-4488:
--------------------------------------
The fact that this has not tripped any test (and we have quite a lot of tests
that flush the store during the test) might indicate that the StoreScanner used
this way only returns false from next(...) if there are no rows left.
Regardless, this violates the InternalScanner contract and might cause problems
in the future.
