Hbase version ：0.90.0
Zookeeper version ：3.3.2
Hadoop version : cloudera 0.20.2+320
Is there any bug in function getMaster ?
While the active hmaster is killed, this function get old hmaster address.
So , it will continue till the old hmaster recover.
In hbase version 0.20.6, This function is called while the Master znode is
created.
while (!stopped && master == null) {
try {
// Do initial RPC setup. The final argument indicates that the RPC
// should retry indefinitely.
master = (HMasterRegionInterface) HBaseRPC.waitForProxy(
HMasterRegionInterface.class, HBaseRPCProtocolVersion.versionID,
masterAddress.getInetSocketAddress(), this.conf, -1,
this.rpcTimeout, this.rpcTimeout);
} catch (IOException e) {
e = e instanceof RemoteException ?
((RemoteException)e).unwrapRemoteException() : e;
if (e instanceof ServerNotRunningException) {
LOG.info("Master isn't available yet, retrying");
} else {
LOG.warn("Unable to connect to master. Retrying. Error was:", e);
}
sleeper.sleep();
}

主题: Re: the region server can't join in the new hmaster while the state become
active from standy
I see the master is waiting and I see the exceptions but there's no
context and the timestamps don't match (what happened in the region
server at the time the second master took over), can you explain
exactly what was done to get in that state? Also could you please tell
use which hbase version you're using?
