HMaster and HRegionServer not working

Hello All, I had installed Hadoop 2.6.0 with Hbase 1.0. Have configured all the settings mentioned in the Apache Website for both hadoop and Hbase. Hadoop runs successfully, but when I Start HBase, I dont see both HMaster and HRegionServer in JPS. Please find below my config files:

<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://hadoopmaster:9000/hbase</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/tmp</value>
</property>
