> Issue Type: Bug
> Components: security

> 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()}}.
