Yufei Gu created YARN-7306:
------------------------------
Summary: Set default RPC timeout to 5 minutes
Key: YARN-7306
URL: https://issues.apache.org/jira/browse/YARN-7306
Project: Hadoop YARN
Issue Type: Improvement
Components: nodemanager, resourcemanager
Reporter: Yufei Gu
Assignee: Yufei Gu
The motivation is well described in HADOOP-11252.

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.
