Java client connection to HBase 0.20.1 problem

[Sławek Trybus]

Hi to everyone in the forum!

I'm getting started with HBase 0.20.1 and I'm trying to prepare dev
environment for web application development based on HBase as storage.

In my test desktop java application I'm getting console output like this:

I'm working on Windows Vista (running my java client application in eclipse)
and HBase is installed on Ubuntu 9.04 installed on VMware. Ubuntu virtual
machine has IP 192.168.219.129.
On Ubuntu I have installed Hadoop 0.20.1 and HBase 0.20.1 working in
Pseudo-Distributed Mode.

Hadoop conf files on Ubuntu:

*conf/core-site.xml*
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>*fs.default.name*</name>
<value>*hdfs://localhost:9000*</value>
</property>
</configuration>

*conf/hdfs-site.xml*

</configuration>

<configuration>
<property>
<name>*mapred.job.tracker*</name>
<value>*localhost:9001*</value>
</property>
</configuration>


HBase conf file on Ubuntu

*conf/hbase-site.xml*
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>*h**base.rootdir*</name>
    <value>*hdfs://localhost:9000/hbase*</value>
    </description>
  </property>
</configuration>



In *classpath *of my java application there are all HBase jars and *
hbase-site.xml* file with content:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>*hbase.rootdir*</name>
    <value>*hdfs://192.168.219.129:9000/hbase*</value>
    </description>
  </property>
  <property>
    <name>*hbase.zookeeper.quorum*</name>
    <value>*192.168.219.129*</value>
  </property>
</configuration>


When I'm connecting to HBase by shell it's working perfectly.
I know that there might be a problem bas content of */etc/hosts* file in
Ubuntu; mine is like this:

*127.0.0.1 localhost ubuntu*
# 127.0.1.1 ubuntu.localdomain ubuntu
# The following lines are desirable for IPv6 capable hosts
# ::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts


I don't know what's wrong in my configuration.
If you could advice I'd be very appreciate because now I can't go further
with my HBase.

Add the following in your /etc/hosts

<ip address> <hostname>

That might be the problem

Restart the network interfaces after you edit the hosts file:

sudo /etc/init.d/networking restart

Hi Amandeep,

Could you be a bit more specific what <ip address> and <hostname>?
Should it be something different than "127.0.1.1    ubuntu" ?

I'm rather a weak linux administrator and not filling well this area.

Hi Saawek,

Replace "127.0.1.1" with the real IP address "192.168.219.129", then
"sudo /etc/init.d/networking restart" as Amandeep suggested.

Thanks,
