Abhishek Modi commented on YARN-3488: ------------------------------------- Tests failures are not related to this change. Ran tests locally and tests are passing. [~rohithsharma] [~vrushalic] [~djp] couldĀ you please review it. Thanks. > AM get timeline service info from RM rather than Application specific > configuration. > ------------------------------------------------------------------------------------ > > Key: YARN-3488 > URL: https://issues.apache.org/jira/browse/YARN-3488 > Project: Hadoop YARN > Issue Type: Sub-task > Components: applications > Reporter: Junping Du > Assignee: Abhishek Modi > Priority: Major > Labels: YARN-5355 > Attachments: YARN-3488.001.patch, YARN-3488.002.patch > > > Since v1 timeline service, we have MR configuration to enable/disable putting > history event to timeline service. For today's v2 timeline service ongoing > effort, currently we have different methods/structures between v1 and v2 for > consuming TimelineClient, so application have to be aware of which version > timeline service get used there. > There are basically two options here: > First option is as current way in DistributedShell or MR to let application > has specific configuration to point out that if enabling ATS and which > version could be, like: MRJobConfig.MAPREDUCE_JOB_EMIT_TIMELINE_DATA, etc. > The other option is to let application to figure out timeline related info > from YARN/RM, it can be done through registerApplicationMaster() in > ApplicationMasterProtocol with return value for service "off", "v1_on", or > "v2_on". > We prefer the latter option because application owner doesn't have to aware > RM/YARN infrastructure details. Please note that we should keep compatible > (consistent behavior with the same setting) with released configurations. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
