Anoop Sam John commented on HBASE-7663:
---------------------------------------
+1 for having a base class like Mutation. +1 for the name Query.
There are many setter and getters which are common for Scan and Get, like
setFilter, setTimeRange, setTimeStamp etc. All these setters are returning
current object for chained call. So moving these to its base class will change
the signature! New methods for Authorizations and acl can be in super class.

> Implement Accumulo-style visibility labels. Consider the following design
> principles:
> - Coprocessor based implementation
> - Minimal to no changes to core code
> - Use KeyValue tags (HBASE-7448) to carry labels
> - Use OperationWithAttributes# {get,set}Attribute for handling visibility
> labels in the API
> - Implement a new filter for evaluating visibility labels as KVs are streamed
> through.
> This approach would be consistent in deployment and API details with other
> per-KV security work, supporting environments where they might be both be
> employed, even stacked on some tables.
> See the parent issue for more discussion.
