After l-namenode1 became active master , it assigned regions:
2015-05-15 12:16:40,432 INFO [master:l-namenode1:60000]
master.RegionStates: Transitioned {6f806bb62b347c992cd243fc909276ff
state=OFFLINE, ts=1431663400432, server=null} to
{6f806bb62b347c992cd243fc909276ff state=OPEN, ts=1431663400432, server=
l-hbase31.data.cn8.qunar.com,60020,1431462584879}
However, l-hbase31 went down:
2015-05-15 12:16:40,508 INFO
[MASTER_SERVER_OPERATIONS-l-namenode1:60000-0]
handler.ServerShutdownHandler: Splitting logs for
l-hbase31.data.cn8.qunar.com,60020,1427789773001 before assignment.
l-namenode1 was restarted :
2015-05-15 12:20:25,322 INFO [main] util.VersionInfo: HBase 0.96.0-hadoop2
2015-05-15 12:20:25,323 INFO [main] util.VersionInfo: Subversion
https://svn.apache.org/repos/asf/hbase/branches/0.96 -r 1531434
However, it went down due to zookeeper session expiration:
2015-05-15 12:20:25,580 WARN [main] zookeeper.ZooKeeperNodeTracker: Can't
get or delete the master znode
org.apache.zookeeper.KeeperException$SessionExpiredException:
KeeperErrorCode = Session expired for /hbase/master
It started again after that and AssignmentManager did a lot of assignments.
Looks like the cluster was operational this time.
Cheers
