[jira] [Updated] (IMPALA-11827) do not cache admission control service's IP address in coordinator
[ https://issues.apache.org/jira/browse/IMPALA-11827?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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 (post a restart) and so we shouldn't cache dynamic addresses.
