Sergey Shelukhin commented on HIVE-11969:
-----------------------------------------

to introduce the same bug that the original patch had - call isOpen() and then
open if false.
> start Tez session in background when starting CLI

> busy.
> This can be done in background, so the AM might get started while the user is
> running local commands and doing other things.
