[jira] [Commented] (HADOOP-17165) Implement service-user feature in
DecayRPCScheduler
[ https://issues.apache.org/jira/browse/HADOOP-17165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17167773#comment-17167773 ]
Takanobu Asanuma commented on HADOOP-17165:
-------------------------------------------
It seems HADOOP-15016 is a more fundamental approach, but it has been a while since the last update.
My proposal is simple that the service-users are just scheduled into the highest-priority queue. I uploaded the patch. Not sure trunk would merge it, but it might help someone else.

> In our cluster, we want to use FairCallQueue to limit heavy users, but not want to restrict certain users who are submitting important requests. This jira proposes to implement the service-user feature that the user is always scheduled high-priority queue.
> According to HADOOP-9640, the initial concept of FCQ has this feature, but not implemented finally.
