Description

Sometimes user runs DemoClient against secure cluster using the following command:

java -cp `hbase classpath` org.apache.hadoop.hbase.thrift2.DemoClient host 9090

This wouldn't work.
DemoClient should detect the presence of secure cluster - e.g. through the following config:

    <property>
      <name>hbase.thrift.authentication.type</name>
      <value>kerberos</value>
    </property>

User can still specify 'false' as the last parameter if the target cluster is insecure.
