Chang Li commented on YARN-4414: -------------------------------- Hi [~xinxianyin], RM HA already disables IPC retries. Also client should try to connect to RM really hard because it's catastrophic failure if it doesn't. Failure to connect to a NM is not. I think we should just make change for NMProxy in this jira. > Nodemanager connection errors are retried at multiple levels > ------------------------------------------------------------ > > Key: YARN-4414 > URL: https://issues.apache.org/jira/browse/YARN-4414 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Affects Versions: 2.7.1, 2.6.2 > Reporter: Jason Lowe > Assignee: Chang Li > Attachments: YARN-4414.1.2.patch, YARN-4414.1.2.patch, > YARN-4414.1.3.patch, YARN-4414.1.patch, YARN-4414.2.patch > > > This is related to YARN-3238. Ran into more scenarios where connection > errors are being retried at multiple levels, like NoRouteToHostException. > The fix for YARN-3238 was too specific, and I think we need a more general > solution to catch a wider array of connection errors that can occur to avoid > retrying them both at the RPC layer and at the NM proxy layer. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
