Xuan Gong commented on YARN-2468: --------------------------------- bq. If we want to use "day" as the unit, shall we allow "double" interval, such that I can say 0.1 day. I think it would be useful for testing purpose (not unit test, but verifying the feature is working on purpose, and the app is using the feature correctly). Thoughts? Add extra YarnConfiguration.DEBUG_LOG_AGGREGATION_SPEED_UP_RATIO for test/debug purpose. New patch also address other comments > Log handling for LRS > -------------------- > > Key: YARN-2468 > URL: https://issues.apache.org/jira/browse/YARN-2468 > Project: Hadoop YARN > Issue Type: Sub-task > Components: log-aggregation, nodemanager, resourcemanager > Reporter: Xuan Gong > Assignee: Xuan Gong > Attachments: YARN-2468.1.patch, YARN-2468.2.patch, YARN-2468.3.patch, > YARN-2468.3.rebase.2.patch, YARN-2468.3.rebase.patch, YARN-2468.4.1.patch, > YARN-2468.4.patch, YARN-2468.5.1.patch, YARN-2468.5.1.patch, > YARN-2468.5.2.patch, YARN-2468.5.3.patch, YARN-2468.5.4.patch, > YARN-2468.5.patch, YARN-2468.6.patch > > > Currently, when application is finished, NM will start to do the log > aggregation. But for Long running service applications, this is not ideal. > The problems we have are: > 1) LRS applications are expected to run for a long time (weeks, months). > 2) Currently, all the container logs (from one NM) will be written into a > single file. The files could become larger and larger. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
