Change subject: IMPALA-8731: Balance queries across multiple executor groups ...................................................................... IMPALA-8731: Balance queries across multiple executor groups This patch adds a new admission control policy that attempts to balance queries across multiple executor groups belonging to the same request pool based on available memory and slots in each executor group. This feature can be enabled by setting the startup flag '-balance_queries_across_executor_groups=true'. The setting is off by default. Testing: - Add e2e tests to verify the default policy and the new policy.
