I had tried zkCli (ls /hbase and get /hbase/master) , but it returns the correct value.
[zk: localhost:2181(CONNECTED) 2] get /hbase/master ip-10-251-27-130:60000 cZxid = 0xa00000032 ctime = Thu Apr 12 20:03:23 EDT 2012 mZxid = 0xa00000032 mtime = Thu Apr 12 20:03:23 EDT 2012 pZxid = 0xa00000032 Also, I do have the namenode listed in my config Here is my hbase-site.xml file: <configuration> <property> <name>hbase.rootdir</name> <value>hdfs://namenode:9000/hbase</value> </property> Henri Pipe On Fri, Apr 13, 2012 at 1:58 AM, N Keywal <nkey...@gmail.com> wrote: > Hi, > > Literally, it means that ZooKeeper is there but the hbase client can't find > the hbase master address in it. > By default, the node used is /hbase/master, and it contains the hostname > and port of the master. > > You can check its content in ZK by doing a "get /hbase/master" in > bin/zkCli.sh (see > > http://zookeeper.apache.org/doc/r3.4.3/zookeeperStarted.html#sc_ConnectingToZooKeeper > ). > > There should be a root cause for this, so it worths looking for other error > messages in the logs (master especially). > > N. > > On Fri, Apr 13, 2012 at 1:23 AM, Henri Pipe <henri.p...@gmail.com> wrote: > > > "client.HConnectionManager$HConnectionImplementation: ZooKeeper available > > but no active master location found" > > > > Having a problem with master startup that I have not seen before. > > > > running the following packages: > > > > hadoop-hbase-0.90.4+49.137-1 > > hadoop-0.20-secondarynamenode-0.20.2+923.197-1 > > hadoop-hbase-thrift-0.90.4+49.137-1 > > hadoop-zookeeper-3.3.4+19.3-1 > > hadoop-0.20-datanode-0.20.2+923.197-1 > > hadoop-0.20-namenode-0.20.2+923.197-1 > > hadoop-0.20-tasktracker-0.20.2+923.197-1 > > hadoop-hbase-regionserver-0.90.4+49.137-1 > > hadoop-zookeeper-server-3.3.4+19.3-1 > > hadoop-0.20-0.20.2+923.197-1 > > hadoop-0.20-jobtracker-0.20.2+923.197-1 > > hadoop-hbase-master-0.90.4+49.137-1 > > [root@ip-10-251-27-130 logs]# java -version > > java version "1.6.0_31" > > Java(TM) SE Runtime Environment (build 1.6.0_31-b04) > > Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode) > > > > I start master and region server on another node. > > > > Master is initialized, but as soon as I try to check the master_status or > > do a zkdump via web interface, it blows up with: > > > > 2012-04-12 19:16:10,453 INFO > > > > > org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation: > > ZooKeeper available but no active master location found > > 2012-04-12 19:16:10,453 INFO > > > > > org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation: > > getMaster attempt 10 of 10 failed; retrying after sleep of 16000 > > > > I am running three zookeepers: > > > > # The number of milliseconds of each tick > > tickTime=2000 > > # The number of ticks that the initial > > # synchronization phase can take > > initLimit=10 > > # The number of ticks that can pass between > > # sending a request and getting an acknowledgement > > syncLimit=5 > > # the directory where the snapshot is stored. > > dataDir=/mnt/zookeeper > > # The maximum number of zookeeper client connections > > maxClientCnxns=2000 > > # the port at which the clients will connect > > clientPort=2181 > > server.1=10.251.27.130:2888:3888 > > server.2=10.250.9.220:2888:3888 > > server.3=10.251.110.50:2888:3888 > > > > I can telnet to the zookeepers just fine. > > > > Here is my hbase-site.xml file: > > > > <configuration> > > <property> > > <name>hbase.rootdir</name> > > <value>hdfs://namenode:9000/hbase</value> > > </property> > > <property> > > <name>hbase.cluster.distributed</name> > > <value>true</value> > > </property> > > <property> > > <name>hbase.zookeeper.quorum</name> > > <value>10.251.27.130,10.250.9.220,10.251.110.50</value> > > </property> > > <property> > > <name>hbase.zookeeper.property.dataDir</name> > > <value>/hadoop/zookeeper/data</value> > > </property> > > <property> > > <name>hbase.zookeeper.property.maxClientCnxns</name> > > <value>2000</value> > > <final>true</final> > > </property> > > </configuration> > > > > Any thoughts?
