I can't use Drill 0.4.0 Release in distributed mode

[刘晓亮]

I installed Drill 0.4.0 Release on three machines with default configuation,  
but I don't uninstall old version Drill. And both have the same configuation.
When I run query on Drill 0.4.0 Release,  only one machine is running from 
zookeeper report, but the old version is ok.  Why?


Thanks.
