---------------------------------------
I think this is the same as IMPALA-4327
> Log a message when --fe_service_threads have been allocated

> Key: IMPALA-8012
> URL: https://issues.apache.org/jira/browse/IMPALA-8012
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend, Clients
> Reporter: Zoram Thanga
> Priority: Major
>
> The maximum number of front end service threads that can be created at any
> time to handle client connections is controlled by the "--fe_service_threads"
> parameter. When all such threads have been allocated, new connection requests
> get queued, and in theory can be spending an indefinite amount of time in the
> queue. Users perceive this as slow impala connection setup time.
> We should log a message when we're near or at --fe_service_threads threads to
> make debugging this situation easier.
