> The code that handles a start scan RPC call checks authentication twice.
> Each call to authenticate takes a bit of time. It would be nice if it only
> did it once.
> At [TabletServer line

> a call to canScan is made which calls authenticate. Then at [TabletServer
> line
> 482|https://github.com/apache/accumulo/blob/rel/1.8.1/server/tserver/src/main/java/org/apache/accumulo/tserver/TabletServer.java#L482]
> a call to check authorizations is made which also authenticates.
