Hi Yang,
Dong's requirement is to run 2 instances in same box, so that one could
for testing and one to serve client.
Per our discussion, I would like to suggest dong to point the second
instance's metadata to different one (we have zookeeper locker for job
engine based on metadata.).
@Dong, could you try it your side?
Thanks.
Best Regards!
