> Limit wait time for getHAServiceState in ObserverReaderProxy

>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: hdfs
>    Affects Versions: 3.4.0
>            Reporter: Xing Lin
>            Assignee: Xing Lin
>            Priority: Minor
>              Labels: pull-request-available
>             Fix For: 3.4.0
>
>
> When namenode HA is enabled and a standby NN is not responsible, we have 
> observed it would take a long time to serve a request, even though we have a 
> healthy observer or active NN. 
> Basically, when a standby is down, the RPC client would (re)try to create 
> socket connection to that standby for _ipc.client.connect.timeout_ _* 
> ipc.client.connect.max.retries.on.timeouts_ before giving up. When we take a 
> heap dump at a standby, the NN still accepts the socket connection but it 
> won't send responses to these RPC requests and we would timeout after 
> _ipc.client.rpc-timeout.ms._ This adds a significantly latency. For clusters 
> at Linkedin, we set _ipc.client.rpc-timeout.ms_ to 120 seconds and thus a 
> request takes more than 2 mins to complete when we take a heap dump at a 
> standby. This has been causing user job failures. 
> We could set _ipc.client.rpc-timeout.ms to_ a smaller value when sending 
> getHAServiceState requests in ObserverReaderProxy (for user rpc requests, we 
> still use the original value from the config). However, that would double the 
> socket connection between clients and the NN (which is a deal-breaker). 
> The proposal is to add a timeout on getHAServiceState() calls in 
> ObserverReaderProxy and we will only wait for the timeout for an NN to 
> respond its HA state. Once we pass that timeout, we will move on to probe the 
> next NN.
