    I installed a single node using HMC on a CentOS 6.3 VMware (hostname is just localhost). Installation and testing of HDFS, MapReduce, and ZooKeeper were successful. I had a failure when it got to testing HBase. After rebooting HDFS start fails. I have Operation log below.

    The operation log is:
    Operation Logs

    “2”: {
    “nodeReport”: [],
    “nodeLogs”: []
    “3”: {
    “nodeReport”: [],
    “nodeLogs”: []
    “4”: {
    “nodeReport”: {
    “nodeLogs”: []

    Thank you in advance for any assistance you can provide.

    Your cluster did not complete installation due to HBase issue.
    After reboot, it assumes NEW installation and tried to restart everything from scratch and format namenode (which is already formatted before) and fail on this:
    hadoop::Namenode::Format/Exec[/tmp/]/returns (notice): ERROR: Namenode directory(s) is non empty. Will not format the namenode. List of non-empty namenode dirs /usr/local/hadoop/hdfs/namenode

    Please, deinstall HMC and puppet, then install HMC and start installation again.

    Make sure that in the service configuration page, you have heap size for HBase Region server set to at least 1024 (region server can not start if heap size is less than 1 Gb)…

    Thank you!
