> HADOOP-9106 introduced a configurable retry timeout when there are socket
> timeouts errors.
> Since the IPC client is used by a wide variety of applications including
> realtime/online ones (like hbase + hdfs), we sometimes need fast fail
> timeouts which are < 3 seconds. Achieving such a timeout for connect is very
> difficult with a 1 second sleep in b/w retries. It would be good to remove
> this sleep.
