Subject [jira] [Commented] (HBASE-15315) Remove always set super user call as high priority
Date Fri, 08 Apr 2016 17:37:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15232539#comment-15232539

Sean Busbey commented on HBASE-15315:
-------------------------------------

It's generally a bad idea to use service principles to launch clients. We could call this
out in our troubleshooting section? It might be worth mentioning in the YCSB docs as well,
if we don't already.

> Current implementation set superuser call as ADMIN_QOS, but we have many customers use
superuser to do normal table operation such as put/get data and so on. If client put much
data during region assignment, RPC from HMaster may timeout because of no handle. so it is
better to remove always set super user call as high priority.
