> Disable ipv6 support on JVM

>
> 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.
