-------------------------------------------
@Jonathan, Any update on this bug ? Given that it was supposed to be solved as
part of 1249 is it now "closeable" ?
> Support for specifying a timestamp and numVersions on a per-column basis

> This is just an idea and it may be better to wait after the planned API
> changes. But I think it would be useful to support fetching different
> timestamps and versions for different columns.
> Example:
> If a row has 2 columns, "col1:" and "col2:" I want to be able to ask for
> (during scan or read time, doesn't matter) 2 versions of "col1:" (maybe even
> between timestamps t1 and t2) but only 1 version of "col2:". This would be
> especially handy if during an MR job you have to read 2 versions of a small
> column, but do not want the overhead of reading 2 versions of every other
> column too....
> (Also, the mechanism is already there. I mean, making the changes to support
> a per-column timestamp/numVersions is ridiculously easy :)
