> -------------------------------------------------------
>
> Key: HDFS-17341
> URL: https://issues.apache.org/jira/browse/HDFS-17341
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 2.10.0, 3.4.0
> Reporter: Lei Yang
> Priority: Major
>
> Some service users today in namenode like ETL, metrics collection accounts
> for many traffic and shouldn't be throttled the same way as other individual
> users in FCQ.
> The idea is to allocate dedicated rpc queues for those service users and
> allocate processing weight for those users.
>
> New configs:
> {code:java}
> "faircallqueue.reserved.users"; // list of service users that are assigned to
> dedicated queue
> "faircallqueue.reserved.users.max"; // max number of service users allowed
> "faircallqueue.reserved.users.capacities"; // custom queue capacities for
> each service user
> "faircallqueue.multiplexer.reserved.weights"; // processing weights for each
> dedicated queue{code}
>
