Eric Newton updated ACCUMULO-1572: ---------------------------------- Assignee: Eric Newton > single node zookeeper failure kills connected accumulo servers > -------------------------------------------------------------- > > Key: ACCUMULO-1572 > URL: https://issues.apache.org/jira/browse/ACCUMULO-1572 > Project: Accumulo > Issue Type: Bug > Components: master, tserver > Affects Versions: 1.5.0 > Reporter: Eric Newton > Assignee: Eric Newton > Priority: Blocker > Fix For: 1.5.1, 1.6.0 > > > Drew Thornton writes on the user mailing list: > {quote} > If one zookeeper node is shutdown/fails/whatever and the rest of the ensemble > stays up, the tablet servers attached as clients to the shutdown node > immediately fail. If one of the clients happens to be the master, the cluster > goes down. > Accumulo does not seem to be failing over to the remaining zookeeper nodes, > and this causes me to restart the individual tablet servers again. > The zookeeper ensemble is very stable and has plenty of > bandwidth/memory/processing, so taking one node down out of five doesn't > crash the zookeepers, just the tablet servers... > {quote} -- This message is automatically generated by JIRA.
