Anoop Sam John commented on HBASE-17095:
----------------------------------------

ScannerResetException is a DoNotRetryIOException and it should come back to client as DNR exception only..   Will see ur patch.

> In {{RsRPCServices.scan}}, most of IOE are thrown as a {{ScannerResetException}}, even when the hfile is corrupt or it cannot be found. The {{ClientScannr.loadCache}} will keep retrying when the exception is {{ScannerResetException}}. We could throw CorruptHFileException and FileNotFoundException directly from server and don't retry the scan in the client.
