> Came across a couple of instances where active master failover happens around the same time as Zookeeper leader failover, leading to stuck HBase client if one of the threads is blocked on one of the ConnectionRegistry rpc calls. 
> ConnectionRegistry APIs are wrapped with CompletableFuture. However, their usages do not have any timeouts, which can potentially lead to the entire client in stuck state indefinitely as we take some global locks. For instance, _getKeepAliveMasterService()_ takes
> {_}masterLock{_}, hence if getting active master from _masterAddressZNode_ gets stuck, we can block any admin operation that needs {_}getKeepAliveMasterService(){_}.
>  
> Sample stacktrace that blocked all client operations that required table descriptor from Admin:
