Please (re-)apply the formatter on the changed files, to ensure that
there's no trailing whitespace and such. I saw a few that stood out in the
command-line git colored output (not sure why the GitHub interface doesn't
highlight them, though). Thanks!
> Arbitrary namespace and table metadata tags
> -------------------------------------------
>
> Key: ACCUMULO-2841
> URL: https://issues.apache.org/jira/browse/ACCUMULO-2841
> Project: Accumulo
> Issue Type: New Feature
> Components: client
> Reporter: Christopher Tubbs
> Assignee: Jenna Huston
> Labels: metadata, newbie
> Fix For: 1.7.0
>
>
> Application-level tags (tagName = tagValue) could be added to tables and
> namespaces, to allow applications to set application-level metadata about a
> namespace or table.
> Use cases include management for billing, administrator notes, date created,
> last ingest time, stats, information about the table's schema... or anything
> else an application might wish to use tags for.
> These tags could be stored in zookeeper, but are probably best stored in the
> metadata table (probably in a separate reserved area of the metadata table,
> ~tag) because they could be arbitrarily large and do not need to be persisted
> in memory.
> This feature would include new APIs to manipulate table / namespace metadata.
> Considerations should be made to ensure users have appropriate permissions to
> add tags to an object.
> This feature could be used to implement ACCUMULO-650.
