It may be good to stretch this to users too - hbase superuser (configured via hbase.superuser) gets higher priority over other users in the RPC handling. That way the superuser can always perform administrative operations on the cluster even if all the normal priority handlers are occupied (for example, we had a situation where all the master's handlers were tied up with many simultaneous createTable RPC calls from multiple users and the master wasn't able to perform any operations initiated by the admin). (Discussed this some with [~enis] and [~elserj]). > Does this make sense to others? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
