Sunil G commented on YARN-6148: ------------------------------- I generally went through whole approach suggested here, and I still feel there are some more grey areas. Could [~varun_saxena] or [~naganarasimha...@apache.org] to put these in a small doc here. I feel this may be needed because there are small feature sets from node label / scheduler is playing impact on MR's blacklisting. Few of them are discussed here, but still its better to brainstorm. To summarize some features which has impact on blacklist are non-exclusive label, move app, default queue's label, preemption of non-exclusive label etc. In hindsight, I feel MR is going to get multiple data sets. Like per-label-node-count, node-report-on-label-change, app-queue-on-change, app-default-label-on-change etc in addition to existing MR blacklist. Its better to get a common consensus here on approach. I thought of looping [~jlowe] and [~leftnoteasy] as changes are proposed in MR and in YARN's interface end. > NM node count reported to AM in Allocate Response should consider requested > node label partitions. > -------------------------------------------------------------------------------------------------- > > Key: YARN-6148 > URL: https://issues.apache.org/jira/browse/YARN-6148 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Varun Saxena > Assignee: Varun Saxena > Attachments: YARN-6148.01.patch > > -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
