Abhishek Rawat updated IMPALA-11827:
------------------------------------
Description:
The Impalad's ExecEnv caches resolved IP address for admission control service:
[https://github.com/apache/impala/blob/master/be/src/runtime/exec-env.h#L301]
The Impala server runs a heart beat thread for admission control service and it
relies on the cached resolved address in ExecEnv:
[https://github.com/apache/impala/blob/master/be/src/service/impala-server.cc#L584]
This breaks when IP address for admission control services changes and so we
shouldn't cache dynamic addresses.
