Christopher Tubbs resolved ACCUMULO-1228.
-----------------------------------------
Resolution: Won't Fix
Fix Version/s: (was: 1.8.0)
I'm closing this for now, because it doesn't seem to make a lot of sense to
keep punting on the fixVersion.
Also, it seems there were a few related issues identified here, and they seem
to need further teasing out, perhaps in some DISCUSS threads on the mailing
list, before proceeding. I would recommend new, more narrowly focused issues be
placed in new, separate JIRAs, if anybody has a use case that warrants
revisiting anything discussed here.
> Allow clients to disable column families and locality groups

> Key: ACCUMULO-1228
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1228
> Project: Accumulo
> Issue Type: New Feature
> Components: client, tserver
> Affects Versions: 1.5.0
> Reporter: William Slacum
> Priority: Minor
>
> There's an inconsistency between what a server is capable of and what a
> client can tell it to do with respect to fetching column families.
> Currently, a user can tell a {{Scanner}} to fetch some set of column
> families. The iterators support not only this, but also the converse where a
> user does not want to retrieve column families. An iterator implementation
> can do this by hand, but a client cannot specifically tell a Scanner to not
> return data from a set of column families. Clients should be able to specify
> this option.
> There also seems to be an inconsistency with how locality groups are defined
> and then utilized. If I want to specify a set of column families as being
> part of a locality group, I have to provide a mapping of locality group name
> to a list of column families. If I want to fetch a locality group, I have to
> get the mapping first, rather than just set which locality group I want to
> use. It'd be more convenient to tell the scanner just to fetch which locality
> groups I want, and have the server know which column families that means.
