Subject: Unable to connect from windows desktop to HBase

Hi,

I'm trying to connect from a Java client running on a Windows desktop machine to a remote
HBase cluster running in the distributed mode(atop 2-node Hadoop cluster).

1.      On the master(namenode)node :
hduser@cldx-1139-1033:~/hadoop_ecosystem/apache_hbase/hbase_installation/hbase-0.94.6.1/bin$
jps
9161 HMaster
4536 SecondaryNameNode
4368 DataNode
4645 JobTracker
8395 Jps
4813 TaskTracker
4179 NameNode
7717 Main



2.       On the slave(datanode)node :


hduser@cldx-1140-1034:~$ jps

5677 HRegionServer

5559 HQuorumPeer

2634 TaskTracker

3260 Jps

2496 DataNode



3.       I also connected to the shell and created a hbase table and also able to scan it
:


hbase(main):004:0> scan 'CUSTOMERS'

ROW                              COLUMN+CELL

 CUSTID12345                     column=CUSTOMER_INFO:EMAIL, timestamp=1365600369284, value=Omkar.Joshi@lntinfotech.com

 CUSTID12345                     column=CUSTOMER_INFO:NAME, timestamp=1365600052104, value=Omkar
Joshi

 CUSTID614                       column=CUSTOMER_INFO:NAME, timestamp=1365601350972, value=Prachi
Shah

2 row(s) in 0.8760 seconds



4.       The hbase-site.xml has the following configurations:


<configuration>

<property>

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

    <value>cldx-1140-1034</value>

    <description>The directory shared by RegionServers.

    </description>

</property>

<property>

    <name>hbase.zookeeper.property.dataDir</name>

    <value>/home/hduser/hadoop_ecosystem/apache_hbase/zk_datadir</value>

    <description>Property from ZooKeeper's config zoo.cfg.

    The directory where the snapshot is stored.

    </description>

</property>

<property>

    <name>hbase.rootdir</name>

    <value>hdfs://cldx-1139-1033:9000/hbase</value>

    <description>The directory shared by RegionServers.</description>

</property>

<property>

    <name>hbase.cluster.distributed</name>

    <value>true</value>

    <description>The mode the cluster will be in. Possible values are false: standalone
and pseudo-distributed setups with managed Zookeeper true: fully-distributed with unmanaged
Zookeeper Quorum (see hbase-env.sh)</description>

</property>

</configuration>



5.       The Hadoop's core-site.xml has the following settings :


<configuration>

<property>

<name>fs.default.name</name>

<value>hdfs://cldx-1139-1033:9000</value>

</property>

</configuration>
