Work Description: tasanuma commented on pull request #2240:
URL: https://github.com/apache/hadoop/pull/2240#issuecomment-684802793
I've read the design documentation for
[HADOOP-15016](https://issues.apache.org/jira/browse/HADOOP-15016) and I
believe that [HADOOP-17165](https://issues.apache.org/jira/browse/HADOOP-17165)
could co-exist with HADOOP-15016.
* HADOOP-17165 adds the service user functionality to the existing
prioritized FairCallQueue, while HADOOP-15016 proposes to add new Reserved
Queue.
* HADOOP-17165 uses the term service user, while HADOOP-15016's POC patch
uses the term reserved user.

> 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.
