------------------------------------------
Summary: Set defaults for idle session / query timeouts and
idle_client_poll_time_s
Key: IMPALA-12911
URL: https://issues.apache.org/jira/browse/IMPALA-12911
Project: IMPALA
Issue Type: Improvement
Reporter: Manish Maheshwari
With https://issues.apache.org/jira/browse/IMPALA-7802 implemented and
https://issues.apache.org/jira/browse/IMPALA-12602 fixed, customers still see
queries in pending to be closed state for a long time. To resolve it OOTB we
want to set sane defaults for idle session / query and idle_client_poll_time_s
so that OOTB Impala closes idle queries and sessions
Recommendations -
idle_client_poll_time_s = 30s (default 30s)
idle_session_timeout = 30m (default 0 = never)
idle_query_timeout = 10m (default 0 = never)
