Subject [jira] [Commented] (YARN-7622) Allow fair-scheduler configuration on HDFS
Date Wed, 03 Jan 2018 23:38:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16310482#comment-16310482

Robert Kanter commented on YARN-7622:

Thanks [~gphillips] and [~wilfreds] for review.  Committed to trunk!

[~gphillips], were you also wanting this to go into branch-2?  If so, we'll need a new patch
- it doesn't apply cleanly (imports) or compile (lambdas).

> The FairScheduler requires the allocation file to be hosted on the local filesystem on
the RM node(s). Allowing HDFS to store the allocation file will provide improved redundancy,
more options for scheduler updates, and RM failover consistency in HA.
