The test passes in Eclipse though.
> [VisibilityController] Stackable ScanLabelGenerators

> Key: HBASE-10916
> URL: https://issues.apache.org/jira/browse/HBASE-10916
> Project: HBase
> Issue Type: Improvement
> Reporter: Andrew Purtell
> Assignee: Anoop Sam John
> Priority: Critical
> Fix For: 0.99.0, 0.98.2

> Attachments: HBASE-10916.patch

>
> The ScanLabelGenerator is used by the VisibilityController to assemble the
> effective label set for a user in the RPC context before processing any
> request. Currently only one implementation of this interface can be
> installed, although which implementation to use can be specified in the site
> file. Instead it should be possible to stack multiple implementations of this
> component the same way we do coprocessors, installed with explicit priority
> with ties broken by a counter, where those implementations installed later in
> the chain have an opportunity to modify the pending effective label set.
