Accessing HBase running in VM with a client on host system

Just to give an added value to users reading this, here is the solution:

Could not resolve the DNS name of cloudera-vm

To fix that I simply added to C:\Windows\System32\drivers\etc\hosts :

192.168.56.101  cloudera-vm

So whenever cloudera-vm is used it is resolved to the apropriate IP.The VM is now running at Host-Only-Network Mode, and is assigned to 192.168.56.101 now.So no port forwarding is necessary.

Just for comparison:

hbase-site.xml

<configuration>  <property>    <name>hbase.zookeeper.quorum</name>    <value>cloudera-vm</value>  </property></configuration>

persistence.xml

<persistence    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"    version="1.0">    <persistence-unit name="hbase-addressbook"        transaction-type="RESOURCE_LOCAL">        <properties>            <property name="datanucleus.ConnectionURL" value="hbase:cloudera-vm" />            <property name="datanucleus.ConnectionUserName" value="" />            <property name="datanucleus.ConnectionPassword" value="" />            <property name="datanucleus.autoCreateSchema" value="true" />            <property name="datanucleus.validateTables" value="false" />            <property name="datanucleus.Optimistic" value="false" />            <property name="datanucleus.validateConstraints" value="false" />        </properties>    </persistence-unit></persistence>

After that I got another error (connection refused although all connection strings were correct) thus I researched for days for the cause.

The solution was to disable IPV6 of Ubuntu running on the VM by appending the following to the file: /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1net.ipv6.conf.default.disable_ipv6 = 1net.ipv6.conf.lo.disable_ipv6 = 1

After reboot everything connects and works correctly :)

I think you can set the configuration clearly in the code ,like this HbaseConfiguration conf = HbaseConfiguration.create();conf.set("hbase.zookeeper.quorum", "ubuntu1,ubuntu2");...maybe help you ..

have you tried a simple:

<property name="connectionURL" value="hbase:master.standalone.hostname:60000"/>
