The node /hbase is not in ZooKeeper

Question

I am a newbie in Hadoop trying to install Hbase in pseudo distributed mode, version hbase-0.98.10.1-hadoop1-bin, with Hadoop 2.5.2 . I am not able to add a table.

Following error continues when I try to create a table :

client.HConnectionManager$HConnectionImplementation: The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

It finally after displaying the error many times (about 50 times) gives the final error as:

ERROR: The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

Latest entry of log file is:

What could be the possible error? Any help is appreciated.

Answer 1

i use it in Talend，when i add hbase connnection in the hadoop cluster, the step 2/2, i choose repository in hadoop cluster,when i write server and port(default 2181),point the button 'Check', the system prompt：

Connection failure. You must change the Database Settings. Caused by: org.apache.hadoop.hbase.MasterNotRunningException: The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master

then,you need add hadoop properties,click the button and add to the property

zookeeper.znode.parent=/hbase-unsecure click ok,then you click 'Check',the system prompt successfull.

Answer 2

Above answer is correct but a bit more lengthy. I was able to solve this problem by just adding following property in hbase-site.xml ( used hbase-1.2.1 )

<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/mnt/data/zookeeper</value>
</property>

I didnt had to create /mnt/data/zookeeper either. Since I was using HBASE as a standalone I didnt had to run Zookeeper infact it gave an error when I did so

the complete hbase-site.xml configuration file looks like

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>file:///mnt/data/hbase</value>
    </property>
   <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/mnt/data/zookeeper</value>
   </property>
</configuration>

        <name>hbase.master</name> 
        <value>hadoop-master:60000</value>
        </property>
</configuration>

make sure zookeeper should be start and dataDir should be exist.

Answer 4

It means the zookeeper has not the node '/hbase',so create a node name '/hbase' in zookeeper.go to the zkCli and run the 'create /hbase "" ' command.

Answer 5

It Just Worked after using a different hbase version. I was using hbase-0.98.10.1-hadoop1-bin, which was not compatible with my hadoop 2.5.2, so I changed hbase version to hbase-X.XX.XX.X-hadoop2-bin (which was compatible for hadoop 2.X ) and followed Apache's installation steps. Thank you all..
