Jason Fehr updated IMPALA-13772:
--------------------------------
Description:
The insert into sys.impala_query_log DML that workload management executes is
cancelled after waiting for 10 seconds. For example, in the case where
admission control queues the query because the request pool is full or
executors are not available.
The short cancel timeframe is caused by the "FETCH_ROWS_TIMEOUT_MS" query
option not being set. Thus, the default of 10 seconds is used.
Additionally, the workload management queries do not time out as expected based
on the value set in the query_log_write_timeout_s coordinator startup flag.
