Subject [jira] [Commented] (HBASE-15315) PriorityFunction.getPriority should consider more about admin/master call and user call
Date Tue, 23 Feb 2016 17:32:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15159250#comment-15159250

Yong Zhang commented on HBASE-15315:
------------------------------------

I do not think just remove super user ADMIN_QOS is enough, for example, scan meta table should
be high priority, but scan user table should not, because meta table scan is more from master.

> PriorityFunction.getPriority should consider more about admin/master call and user call

> Current implementation set superuser call as ADMIN_QOS, but we have many customers use
superuser to normal such as put, get data, and if client put much data during region assignment,
RPC from HMaster may timeout because of no handle. so it is better to split the admin/master
call and user normal call with data operation.
