Cloudera namenode not starting due to ulimit error

Hi,
I am trying to start the namenode using the cloudera package, but it fails. Checking the log, I found it is failing on ulimit. Can anyone tell what this error is exactly. I gave permissions 777 also for the /data directories but still did not work. I am trying to have single node cluster on CentOS 7 using google cloud Iaas.

root@hadoop admin]# sudo service hadoop-hdfs-namenode start
starting namenode, logging to /var/log/hadoop-hdfs/hadoop-hdfs-namenode-hadoop.out

I did not see the reply. It was my problem. I was looking in to .out file instead of .log. Its solved.
