Change subject: IMPALA-7800: Reject new connections after --fe_service_threads ...................................................................... IMPALA-7800: Reject new connections after --fe_service_threads The current implementation of the FE thrift server waits indefinitely to open the new session, if the maximum number of FE service threads specified by --fe_service_threads has been allocated. This patch introduces a startup flag to control how the server should treat new connection requests if we have run out of the configured number of server threads. By default we retain the current behavior. If --reject_request_on_max_fe_threads=true, however, the new connection requests are rejected by the server. Testing: Added a new custom cluster test suite to exercise the new code. Ran core tests.
