[jira] [Commented] (MESOS-7402) Allocated quota of a child role should be also charged on all ancestors of that role

["Qian Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-7402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15975979#comment-15975979 ]

In another word, allocation made for quota of a/b should also be charged from the quota of its parent.

[~guoger] Can you please elaborate a bit more about "charged from the quota of its parent"? I think in [~neilc]'s patch (https://reviews.apache.org/r/57254/), the allocations made to the child role are already counted into the allocation of parent role.

> Consider following case: role {{a}} is quota'd with resource 100, role {{a/b}} is quota'd with resource 40. In current implementation, quota of parent role is actually the aggregation of quota in whole subtree, including itself. Therefore, the internal node of {{a}} is actually quota'd with 60, instead of 100. In another word, allocation made for quota of {{a/b}} should also be charged from the quota of its parent.
