Stand alone HBase on local file system getting zoo

Hi guys I am trying to follow the quick start of HBase and start an HBase on the local file system( without using HDFS ) However when I start the shell using ./hbase shell and type "status" I get zookeeper error ?!

hbase(main):001:0> status
14/01/07 12:44:48 ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries
14/01/07 12:44:48 WARN zookeeper.ZKUtil: hconnection Unable to set watcher on znode (/hbase/hbaseid)
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid

//......... ect .....

Here is my config file ( hbase-site.xml )

<?xml version="1.0"?>

      For example, "host1.mydomain.com,host2.mydomain.com,host3.mydomain.com".
      By default this is set to localhost for local and pseudo-distributed modes
      of operation. For a fully-distributed setup, this should be set to a full
      list of ZooKeeper quorum servers. If HBASE_MANAGES_ZK is set in hbase-env.sh
      this is the list of servers which we will start/stop ZooKeeper on.

Any suggestions ?

回答1:

Your zookeeper quorum name must be the hostname of your machine and must also be present in the /etc/hosts file. Try restarting the network after this.

回答2:

The problem is here (in your conf - conf/hbase-site.xml):

<name>hbase.zookeeper.quorum</name>
      <value>localhost</value>

As the error "ERROR zookeeper.RecoverableZooKeeper: ZooKeeper exists failed after 3 retries" indicates there is some problem with your zookeeper.quorum directive. Or Before staring the HBase shell you can verify if the ZKQuorum is up, using:

$ jps

the command will list all the java processes on the machine i.e. the probable output has to be:

62019 Jps
61098 HMaster        
61233 HRegionServer     
61003 HQuorumPeer

Solution:

In your HBase directory, first stop the HBase:

$ ./bin/stop-hbase.sh

If you're trying to work out the 'standalone HBase' example - stick to the minimum conf provided in the example:

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>file:///home/adio/workspace/hadoop/hbase/directories/hbase</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/home/adio/workspace/hadoop/hbase/directories/zookeeper</value>
  </property>
</configuration>

i.e. your conf/hbase-site.xml should have the above content.

Once set, now start the HBase again:
