Subject [jira] [Commented] (HBASE-13375) Provide HBase superuser higher priority over other users in the RPC handling
Date Fri, 03 Apr 2015 19:27:53 GMT

Srikanth Srungarapu commented on HBASE-13375:
---------------------------------------------

Looks like getSystemAndSuperUsers have more wider applicability besides VC. What do you think
of moving it to sayd hbase-common module?
{code}
+      List<String> superUsers =
+        VisibilityUtils.getSystemAndSuperUsers(rpcServices.getConfiguration()).getFirst();
{code}

> HBASE-13351 annotates Master RPCs so that RegionServer RPCs are treated with a higher
priority compared to user RPCs (and they are handled by a separate set of handlers, etc.).
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?
