[jira] [Created] (HADOOP-15321) Reduce the RPC Client max retries on timeouts

Xiao Chen created HADOOP-15321:
----------------------------------

             Summary: Reduce the RPC Client max retries on timeouts
                 Key: HADOOP-15321
                 URL: https://issues.apache.org/jira/browse/HADOOP-15321
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
            Reporter: Xiao Chen
            Assignee: Xiao Chen


Currently, the [default|https://github.com/apache/hadoop/blob/branch-3.0.0/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/CommonConfigurationKeysPublic.java#L379] number of retries when IPC client catch a {{ConnectTimeoutException}} is 45. This seems unreasonably high.

Given the IPC client timeout is by default 60 seconds, if a DN host is shutdown the client will retry for 45 minutes until aborting. (If host is there but process down, it would throw a connection refused immediately, which is cool)

Creating this Jira to discuss whether we can reduce that to a reasonable number.
