Eric Payne commented on YARN-10505: ----------------------------------- Thanks for clearing that up! > Extend the maximum-capacity property to support Fair Scheduler migration > ------------------------------------------------------------------------ > > Key: YARN-10505 > URL: https://issues.apache.org/jira/browse/YARN-10505 > Project: Hadoop YARN > Issue Type: Sub-task > Components: capacity scheduler > Reporter: Benjamin Teke > Assignee: Benjamin Teke > Priority: Major > > Currently Fair Scheduler supports the following 3 kinds of settings: > * Single percentage (relative to parent) i.e. "X%" > * A set of percentages (relative to parent) i.e. "X% cpu, Y% memory" > * Absolute resources i.e. "X mb, Y vcores" > Please note, that the new, recommended format does not support the single > percentage mode, only the last 2, like: “vcores=X, memory-mb=Y” or > “vcores=X%, memory-mb=Y%” respectively. > Tasks to accomplish: > # It is recommended that all three formats are supported for > maximum-capacity in CS after introducing weight mode. > # Also we want to introduce the percentage modes relative to the cluster, > not the parent, i.e The property root.users.maximum-capacity will mean one of > the following things: > ## Either Parent Percentage: maximum capacity relative to its parent. If > it’s set to 50, then it means that the capacity is capped with respect to the > parent. This can be covered by the current format, no change there. > ## Or Cluster Percentage: maximum capacity expressed as a percentage of the > overall cluster capacity. This case is the new scenario, for example: > {{yarn.scheduler.capacity.root.users.max-capacity = c:50%}} > {{yarn.scheduler.capacity.root.users.max-capacity = c:50%, c:30%}} -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
