Subject [jira] [Created] (HBASE-17095) The ClientSimpleScannr cannot be stopped if the hfile is corrupt or cannot found

------------------------------------

             Summary: The ClientSimpleScannr cannot be stopped if the hfile is corrupt or
cannot found
                 Key: HBASE-17095
                 URL: https://issues.apache.org/jira/browse/HBASE-17095
             Project: HBase
          Issue Type: Bug
          Components: Client, regionserver
            Reporter: Jingcheng Du
            Assignee: Jingcheng Du


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 those exceptions directly
from server and don't retry the scan in the client.
