    The patch looks straightforward. This patch does not affect any tests. The 
unit test was failed due to time zone issue (TAJO-1234). I'll commit it shortly.

> This is not a critial issue, but each Tajo components internally use ipv4 
> address. Without this option, JVM will try to load ipv6 stacks on jvm 
> processes and bind itself with ipv6 addresses. It could waste JVM resources 
> and could be decreased network performance. If we don't have a plan to 
> support ipv6 address, it could be better to turn off ipv6 support.
