i create a new client host outside the cluster by copying directory hdp & current & /etc/<conf> of one of the cluster's host

i can run hive

but when i run hive through different users at the same time,there is only one can be running ,others will wait until the running one finish.

how to change it?

I believe this is related to the setting on your capacity scheduler. If you didn't setup the scheduler, then all resources will be allocated to the first user, and other user have to wait. Please refer the documentation for detail:
