Hudson commented on HBASE-4246: ------------------------------- Integrated in HBase-TRUNK-on-Hadoop-2.0.0 #351 (See [https://builds.apache.org/job/HBase-TRUNK-on-Hadoop-2.0.0/351/]) Add to troubleshooting a note on zk buffer size issue when lots of regions -- hbase-4246 (Revision 1434087) Result = FAILURE > Cluster with too many regions cannot withstand some master failover scenarios > ----------------------------------------------------------------------------- > > Key: HBASE-4246 > URL: https://issues.apache.org/jira/browse/HBASE-4246 > Project: HBase > Issue Type: Bug > Components: master, Zookeeper > Affects Versions: 0.90.4 > Reporter: Todd Lipcon > Fix For: 0.96.0 > > > We ran into the following sequence of events: > - master startup failed after only ROOT had been assigned (for another reason) > - restarted the master without restarting other servers. Since there was at > least one region assigned, it went through the failover code path > - master scanned META and inserted every region into /hbase/unassigned in ZK. > - then, it called "listChildren" on the /hbase/unassigned znode, and crashed > with "Packet len6080218 is out of range!" since the IPC response was larger > than the default maximum. -- This message is automatically generated by JIRA.
