Description

In HBASE-16604, we fixed a case where scanner retries was causing the scan to miss some data in case the scanner is left with a dirty state (like a half-seeked KVHeap).

The patch introduced a minor compatibility issue, because now if a coprocessor throws DNRIOE, we still retry the ClientScanner indefinitely.

The test ServerExceptionIT in Phoenix is failing because of this with HBASE-16604.
