Anoop Sam John commented on HBASE-10916: ---------------------------------------- bq.whether we should be calling these "ScanLabelGenerators" or "ScanAuthsGenerators" +1 > [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 > Fix For: 0.99.0, 0.98.2 > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
