    hi every body,
    i am conducting a manula installation of HDP 1.2.0… i have reached to the stage of conducting hbase smoke test. i can successfully connect to the hbase shell.. but when issuing commands i get
    **************************************************************************************
    hbase(main):002:0> create ‘usertable’, ‘family’

    ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

    Here is some help for this command:
    Create table; pass table name, a dictionary of specifications per
    column family, and optionally a dictionary of table configuration.
    Dictionaries are described below in the GENERAL NOTES section.
    Examples:

    hbase> create ‘t1’, {NAME => ‘f1’, VERSIONS => 5}
    hbase> create ‘t1’, {NAME => ‘f1’}, {NAME => ‘f2’}, {NAME => ‘f3’}
    hbase> # The above in shorthand would be the following:
    hbase> create ‘t1’, ‘f1’, ‘f2’, ‘f3’
    hbase> create ‘t1’, {NAME => ‘f1’, VERSIONS => 1, TTL => 2592000, BLOCKCACHE => true}
    hbase> create ‘t1’, ‘f1′, {SPLITS => [’10’, ’20’, ’30’, ’40’]}
    hbase> create ‘t1’, ‘f1’, {SPLITS_FILE => ‘splits.txt’}
    hbase> # Optionally pre-split the table into NUMREGIONS, using
    hbase> # SPLITALGO (“HexStringSplit”, “UniformSplit” or classname)
    hbase> create ‘t1’, ‘f1’, {NUMREGIONS => 15, SPLITALGO => ‘HexStringSplit’}
    **************************************************************************************
    i am doing a single node installation..

    Hi Zuhair,

    When you run the following command:

    <JAVA_HOME>/jps

    do you get a HMaster and a QuorumPeerMain in the listing? If not then this is why you are getting the errot you are seeing.

    Thanks,
    Ted.

    hi Ted,

    thanks for the tip. i have resolved the issue. it all relates to DNS binding and resolution.
    it becomes so confusing.. sometimes address binding will work with Localhost and sometimes it works with FQDN..

    regards,
