------------------------------------------------------------------
Tested the recent patch on cluster, clogging the nodes with spurious llap
processes :)
The CLI looks like the attached while the corresponding Tez app is submitted
but not running. When I stopped the llap cluster, the query started running.
I could run queries (such as "use database") without Tez AM (see OK above the
query start).
Query also compiled without waiting for AM.

> Tez session spins up AM, which can cause delays, esp. if the cluster is very
> busy.
> This can be done in background, so the AM might get started while the user is
> running local commands and doing other things.
