Ted Yu commented on HBASE-16829:
--------------------------------

Thanks to Josh who found the case where mismatched user name for hbase.thrift.kerberos.principal led to the mysterious SocketTimeoutException.

> Sometimes user runs DemoClient against secure cluster using the following command:
> {code}
> java -cp `hbase classpath` org.apache.hadoop.hbase.thrift2.DemoClient host 9090
> {code}
> This wouldn't work.
> DemoClient should detect the presence of secure cluster - e.g. through the following config:
> {code}
>     <property>
>       <name>hbase.thrift.authentication.type</name>
>       <value>kerberos</value>
>     </property>
> {code}
> User can still specify 'false' as the last parameter if the target cluster is insecure.
