Subject [jira] [Commented] (ACCUMULO-4799) In tablet server start scan authenticates twice
Date Thu, 08 Feb 2018 23:19:00 GMT


Christopher Tubbs commented on ACCUMULO-4799:

We need to introduce the concept of an authenticated "User" object on the server-side that
is tied to that specific RPC request. This would be similar to servlet security context authenticated
users which are established after a call to HttpServletRequest.login().

>                 URL:
>             Project: Accumulo
>          Issue Type: Improvement
>    Affects Versions: 1.7.3, 1.8.1
>            Reporter: Keith Turner
>            Priority: Major
>             Fix For: 1.9.0, 2.0.0
> 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 479|] a
call to canScan is made which calls authenticate.  Then at [TabletServer line 482|] a
call to check authorizations is made which also authenticates.
