[jira] [Comment Edited] (HBASE-17095) The ClientSimpleScanner keeps
retrying if the hfile is corrupt or cannot found
[ https://issues.apache.org/jira/browse/HBASE-17095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15672921#comment-15672921 ]

------------------------------------------------------------------
So we throw back CorruptedHFileException or FNFE back to client now so that we dont end up throwing ScannerResetException. It will be better if u can create a new HBase specific exception, extending DNRIOE for the HFile not found case. Being more generic and checking all possible cases, am ok we can do in another issue
Else +1

> 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.
