Tsuyoshi OZAWA commented on YARN-2052: -------------------------------------- Jian, thank you for clarifying. I'm working to address the comments. Please wait a moment. > ContainerId creation after work preserving restart is broken > ------------------------------------------------------------ > > Key: YARN-2052 > URL: https://issues.apache.org/jira/browse/YARN-2052 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Tsuyoshi OZAWA > Assignee: Tsuyoshi OZAWA > Attachments: YARN-2052.1.patch, YARN-2052.2.patch, YARN-2052.3.patch, > YARN-2052.4.patch > > > Container ids are made unique by using the app identifier and appending a > monotonically increasing sequence number to it. Since container creation is a > high churn activity the RM does not store the sequence number per app. So > after restart it does not know what the new sequence number should be for new > allocations. -- This message was sent by Atlassian JIRA (v6.2#6252)
