Subject [jira] [Commented] (ACCUMULO-2885) User manual does not define what namespaces are or how they work
Date Tue, 17 Jun 2014 20:47:10 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14034341#comment-14034341

Christopher Tubbs commented on ACCUMULO-2885:
---------------------------------------------

I'm not sure what guidelines you're referring to, except that I mentioned previously to you
(in implementing ACCUMULO-378) that the reserved accumulo namespace was for internal use,
and that add-on features should use a user-defined namespace (this is enforced... users can't
create tables in the accumulo namespace anyway).

Any general description of namespaces should describe how they work (hierarchical configuration)
with some use cases to clarify how this helps users (convenience of configuring several tables
with similar permissions, for example).

If I have time, I'll revisit this issue myself. In the meantime, if somebody wants to pick
it up, I'd be happy to review the documentation.

> In adding table namespaces to the notable features page, I noticed that we don't have
any user manual documentation for them.
> It would be good at a minimum to define what a table namespace is, describe the system
and default namespace, inform the inspiration in implementation from relational databases
(database.table), and that a table is now fully qualified by {{namespace.table}}.
> Other info?
