[jira] [Created] (KNOX-2134) Add caching to ZookeeperRemoteAliasService

Philip Zampino created KNOX-2134:
------------------------------------

             Summary: Add caching to ZookeeperRemoteAliasService
                 Key: KNOX-2134
                 URL: https://issues.apache.org/jira/browse/KNOX-2134
             Project: Apache Knox
          Issue Type: Bug
          Components: Server
    Affects Versions: 1.3.0
            Reporter: Philip Zampino
            Assignee: Philip Zampino
             Fix For: 1.4.0


The ZookeeperRemoteAliasService implementation always goes to ZooKeeper to retrieve alias data. Instead, it should cache the data locally to make password retrieval much faster.

The implementation already receives pushes from ZooKeeper when alias znodes change, so instead of only updating the associated local alias service, it can also update its own cache.

This way, it only ever needs to go to ZooKeeper for add/remove operations.
