Hi All,
I have installed Hadoop 1.2.1 in Fedora 20 Linux OS. I am using the single node
configuration.
Hadoop is up.
[root@localhost hbase-0.98.5-hadoop1]# jps
6153 JobTracker
6272 TaskTracker
6061 SecondaryNameNode
8594 HQuorumPeer
5938 DataNode
5816 NameNode
8917 Jps
Core-site.xml file -
<configuration>
<property>

</property>
</configuration>
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>

Configuration related to Hbase is as follows,
<configuration>

<value>true</value>

Hosts file,
[root@localhost ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain
::1 localhost6.localdomain6 localhost6
After starting the hbase, I am getting the following
[root@localhost hbase-0.98.5-hadoop1]# ./bin/start-hbase.sh
