Subject Hbase 0.98 not able to connect to Hadoop 2.4 running on VM
Date Mon, 01 Sep 2014 12:05:18 GMT
Hi

I have installed a hadoop 2.4 cluster on a virtual machine and everything
is up and running. Here is my settings in core-site.xml

<configuration>
  <property>
    <name>fs.default.name</name>
    <value>hdfs://localhost:9000</value>
  </property>
</configuration>

Hbase settings:

<configuration>

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

 <property>
    <name>hbase.security.authentication</name>
    <value>simple</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>dfs.replication</name>
    <value>1</value>
 </property>
 <property>
 <name>hbase.zookeeper.quorum</name>
 <value>akhettar</value>
 </property>
 <property>
 <name>hbase.security.authentication</name>
 <value>simple</value>
 </property>
 <property>
 <name>hbase.security.authorization</name>
 <value>true</value>
 </property>
 <property>
 <name>hbase.coprocessor.master.classes</name>
 <value>org.apache.hadoop.hbase.security.access.AccessController</value>
 </property>
 <property>
 <name>hbase.coprocessor.region.classes</name>
 <value>org.apache.hadoop.hbase.security.access.AccessController</value>
 </property>
</configuration>

I am running Hbase 0.98 version on a Macbook which is hosting the Hadoop
VM. When I try to start hbase master I get the error below. When i try to
telnet from my macbook onto the VM: telnet hadoop 9000 I get connection
refused too. I can telnet  to port 9000 from the VM on which hadoop is
running through.

So my guess is that it's nothing to do with hbase configuration. The port
is closed to outside communication. I can telnet though from my machine to
the VM on other ports like 50070.

Any ideas?

Thanks

Ayache
