> Key: HADOOP-14940

> Project: Hadoop Common
> Issue Type: Improvement
> Reporter: Yufei Gu

> The motivation is well described in HADOOP-11252.
> {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.
> {quote}
> 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.
