> The RPC client has a default timeout set to 0 when no timeout is passed in. 
> This means that the network connection created will not timeout when used to 
> write data. The issue has shown in YARN-2578 and HDFS-4858. Timeouts for 
> writes then fall back to the tcp level retry (configured via tcp_retries2) 
> and timeouts between the 15-30 minutes. Which is too long for a default 
> behaviour.
> Using 0 as the default value for timeout is incorrect. We should use a sane 
> value for the timeout and the "ipc.ping.interval" configuration value is a 
> logical choice for it. The default behaviour should be changed from 0 to the 
> value read for the ping interval from the Configuration.
> Fixing it in common makes more sense than finding and changing all other 
> points in the code that do not pass in a timeout.
> Offending code lines:
