> {quote}
> 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.

> However, HADOOP-11252 didn't set the default value to a meaningful timeout(it is zero, which means infinity). User will still hit this issue by default. Maybe we should set the default value to a meaningful one.
