Hbase Hadoop integration issue - hadoop

Question

I am trying to configure Hbase in pseudo distributed mode integrated with Hadoop which is already running in pseudo distributed mode. Hbase-master fails to start.
1.
hbase-site.xml looks like below:
<configuration>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:8030/hbase</value>
</property>
<!-- <property>
<name>hbase.rootdir</name>
<value>file:/home/hadoop/HBase/HFiles</value>
</property> -->
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/hadoop/zookeeper</value>
</property>
</configuration>
hbase-master fails to start and below error is written in hbase-root-master-bdhost.log

I'm using hadoop 2.6.3 and hbase 1.1.2 on Fedora Linux release 21.
Tried disabling selinux, ipv6 but that did not help.
Any pointer is much appreciated?
Thanks.

Answer 1

In the following property try giving the name as rootDir (with an uppercase D) and let me know if it works. Of course make sure the HDFS is running on the port mentioned in the property.
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:8030/hbase</value>
</property>
