------------------------------------
Summary: 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
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.
