Hbase connection problems and failed to create table

Question

I'm running a multi-node cluster; I'm using hadoop-1.0.3(on both), Hbase-0.94.2(on both) and zookeeper-3.4.6(only master)

master:192.168.0.1 slave:192.168.0.2

Hbase is not running perfectly and I faced problems while trying to create a table on hbase and of course I can't access HBase status UI on http://master:60010 please Help!!

Here is all my configuration files :

(hadoop conf) core-site.xml: (same configuration on both master and slave)

 <configuration>
<property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:54310</value>
 </property>
</configuration>

(hbase conf) hbase-site.xml:

<configuration>

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

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

<property>
      <name>hbase.zookeeper.quorum</name>
      <value>master,slave</value>
</property>

<property>
        <name>hbase.zookeeper.property.clientPort</name>
        <value>2222</value>
</property>

<property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/usr/local/hadoop/zookeeper</value>
</property>

</configuration>

/etc/hosts and :

192.168.0.1 master
192.168.0.2 slave

regionservers:

master
slave

here is the log file : hbase-hduser-regionserver-master.log

I think instead localhost in core-site.xml file use master.

And add slave nodes hosts to slave file in hadoop directory.

And both master & slave nodes core-site.xml file look like this:

<configuration>
<property>
  <name>fs.default.name</name>
  <value>hdfs://master:54310</value>
 </property>
</configuration>

master and slave hosts should be present in both regionservers file if you make present zookeeper in both.
