Rohith commented on YARN-3094: ------------------------------ Thanks [~hex108] for reporting the issue and for your contributions. Patch looks to me good. Can you add tests for this? And could you give some general information like # How many RUNNING applications are running in cluster? # What is the AM liveliness timeout configured in cluster? > reset timer for liveness monitors after RM recovery > --------------------------------------------------- > > Key: YARN-3094 > URL: https://issues.apache.org/jira/browse/YARN-3094 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.6.0 > Reporter: Jun Gong > Assignee: Jun Gong > Attachments: YARN-3094.patch > > > When RM restarts, it will recover RMAppAttempts and registry them to > AMLivenessMonitor if they are not in final state. AM will time out in RM if > the recover process takes long time due to some reasons(e.g. too many apps). > In our system, we found the recover process took about 3 mins, and all AM > time out. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
