     [ https://issues.apache.org/jira/browse/HBASE-4441?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-4441.
--------------------------
    Resolution: Won't Fix

This is old. We have some prioritization going on now based off annotations, whether system table, type of request... (if superuser)....

> Currently we have a simple QOS model where requests to user tables are using one set of handlers and requests to catalog tables and other administrative functions are using another set. I'm wondering if it's worth expending this model:
>  - Do we want to support different priorities for different tables/users (when security's enabled)/operations?
>  - Do we want finer granularity?
> There's also issues like HBASE-4280 that exposes a case where RS communicate between each other and can potentially deadlock if some slowness is going on.
