> We should recommend and not enforce secure Hadoop underneath as a requirement
> to run secure HBase.
> Few of our customers have HBase clusters which expose only HBase services to
> outside the physical network and no other services (including ssh) are
> accessible from outside of such cluster.
> However they are forced to setup secure Hadoop and incur the penalty of
> security overhead at filesystem layer even if they do not need to.
> The following code tests for both secure HBase and secure Hadoop.
> {code:title=org.apache.hadoop.hbase.security.User|borderStyle=solid}
> /**
> * Returns whether or not secure authentication is enabled for HBase. Note
> that
> * HBase security requires HDFS security to provide any guarantees, so this
> requires that
> * both <code>hbase.security.authentication</code> and
> <code>hadoop.security.authentication</code>
> * are set to <code>kerberos</code>.
> */
> public static boolean isHBaseSecurityEnabled(Configuration conf) {
> return "kerberos".equalsIgnoreCase(conf.get(HBASE_SECURITY_CONF_KEY)) &&
> "kerberos".equalsIgnoreCase(
> conf.get(CommonConfigurationKeys.HADOOP_SECURITY_AUTHENTICATION));
> }
> {code}
> What is worse that if {{"hadoop.security.authentication"}} is not set to
> {{"kerberos"}} (undocumented at http://hbase.apache.org/book/security.html),
> all other configuration have no impact and HBase RPCs silently switch back to
> unsecured mode.
