I find the issue. issue was  with my core-site.xml   

below propery name was not correct.
<name>fs.defaultFS</name>

Please chek this log dile   /var/log/hadoop-hdfs/hadoop-hdfs-namenode-hadoop.cluster.com.log this log file rather than var/log/hadoop-hdfs/hadoop-hdfs-namenode-hadoop.cluster.com.out file

now able to start the name node.
