Subject [jira] [Created] (HBASE-7285) HMaster fails to start with secure Hadoop

------------------------------------

             Summary: HMaster fails to start with secure Hadoop
                 Key: HBASE-7285
                 URL: https://issues.apache.org/jira/browse/HBASE-7285
             Project: HBase
          Issue Type: Bug
          Components: security
    Affects Versions: 0.96.0
            Reporter: Gary Helmling


In current trunk, HMaster will fail to start with secure Hadoop if the user starting the process
has not obtained a kerberos TGT.  The user starting the process should not be required to
have a TGT, as the HMaster process self logs in using the configured keytab and principal.

This is due to a log line in the HMaster constructor executing prior to the {{User.login()}}
step:
{code}
    LOG.info("hbase.rootdir=" + FSUtils.getRootDir(this.conf) +
        ", hbase.cluster.distributed=" + this.conf.getBoolean("hbase.cluster.distributed",
false));
{code}

Here the FSUtils.getRootDir() winds up hitting the NameNode.  The fix is trivial, moving the
log line to follow {{User.login()}}.
