Chao Sun commented on HDFS-15502:
---------------------------------
[~tasanuma] seems this JIRA is very similar to HADOOP-15016? this also should
be a HADOOP jira rather than HDFS.
> Implement service-user feature in DecayRPCScheduler
> ---------------------------------------------------

> Key: HDFS-15502
> URL: https://issues.apache.org/jira/browse/HDFS-15502
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Takanobu Asanuma
> Assignee: Takanobu Asanuma
> Priority: Major
>
> 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.
