-------------------------------------------
Hi [~Eungsop Yoo] , will this proposal result in a full server meta cache clear
if there is a CallTimeoutException for a request to a single region on a
server?
> Clear all meta caches of the server on which hardware failure related
> exceptions occurred

> CallTimeoutException and ConnectException might be caused by a network or
> hardware issue of that server. We might not be able to connect to that server
> for a while. So we have to clear all meta caches of the server on which
> hardware failure related exceptions occurred. If we don't clear the caches,
> we might get the same exceptions as many times as the number of location
> caches of that server.

> We already have ClusterStatusPublisher/Listener feature. But it is not
> possible to use this feature in some infrastructure environments like me.
