Anoop Sam John commented on HBASE-15378: ---------------------------------------- I see. Did not see that new Filter include/skip cells conditionally. I thought it is for sleep purpose only. Fine.. bq.serverHasMoreResults = callable.getServerHasMoreResults() && partialResults.isEmpty(); This change really needed? +1 on patch. > Scanner can not handle a heartbeat message with no results > ---------------------------------------------------------- > > Key: HBASE-15378 > URL: https://issues.apache.org/jira/browse/HBASE-15378 > Project: HBase > Issue Type: Bug > Components: dataloss, Scanners > Affects Versions: 1.2.0, 1.1.3 > Reporter: Phil Yang > Assignee: Phil Yang > Priority: Critical > Attachments: HBASE-15378-v1.txt, HBASE-15378-v2.txt, > HBASE-15378-v3.txt > > > When a RS scanner get a TIME_LIMIT_REACHED_MID_ROW state, they will stop > scanning and send back what it has read to client and mark the message as a > heartbeat message. If there is no cell has been read, it will be an empty > response. > However, ClientScanner only handles the situation that the client gets an > empty heartbeat and its cache is not empty. If the cache is empty too, it > will be regarded as end-of-region and open a new scanner for next region. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
