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.
