Guangyuan Feng updated KYLIN-5545:
----------------------------------
Description:
There are two issues will decrease the stability of Kylin:
# Missed some places to cancel the planning/running queries if occurred
interruptions, leading to the useless consumptions of calculating resources.
# Don't limit the number of queries that can be pushed down, leading to too
many queries to run, evenly to a OOM.
So it's great to have a PR to improve/solve the above issues.
