> 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 have a configurable parameter to reduce this sleep.
