Christopher Tubbs commented on ACCUMULO-891:
--------------------------------------------
Due to the thrift issue, I can make the list immutable, but not the actual
ByteBuffers.
> Authorizations not actually immutable
> -------------------------------------
>
> Key: ACCUMULO-891
> URL: https://issues.apache.org/jira/browse/ACCUMULO-891
> Project: Accumulo
> Issue Type: Improvement
> Components: client
> Affects Versions: 1.4.2
> Reporter: Mike Drob
> Assignee: Christopher Tubbs
> Priority: Minor
> Labels: newbie
> Fix For: 1.6.0
>
> Attachments: ACCUMULO-891.v1.patch, AuthorizationsTest.java
>
>
> Instances of {{Authorizations}} are not actually immutable, despite the API
> making it seem like they are. A user can make changes that will write-through
> to the backing data by using the ByteBuffer getter.
> This is a potential issue if a trusted application acts as a connection
> broker between accumulo and untrusted clients.
