Subject Difficulty in use Hbase fully distributed mode
Date Mon, 18 Jul 2011 07:22:22 GMT
Hi,

I am new user for the hbase and I have trouble in starting HBase.
I am using the hadoop-0.20.2, zookeeper 3.3.3 and Hbase 0.90.1
My conf/hbase-site.xml is


<property>
        <name>hbase.rootdir</name>
        <value>hdfs://192.168.107.142:54310/hbase</value>
</property>

<property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
</property>

<property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2181</value>
</property>

<property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/home/hadoop/zookeeperdata</value>
</property>

<property>
        <name>hbase.master.port</name>
        <value>60000</value>
</property>

<property>
        <name>hbase.zookeeper.quorum</name>
        <value>192.168.107.142,192.168.107.149,192.168.106.202</value>
</property>
My Hadoop and zookeeper are working perfectly but when i started the HBase ,I 
got the following errors in log. Please give me the solution for this problem
