     [ https://issues.apache.org/jira/browse/ACCUMULO-1228?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.

> 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.
