> This might be a specific use case.  But we have some regions which are no longer written
to (due to the key).  Those regions have 1 store file and they are very old, they haven't
been written to in a while.  We still use these regions to read from so locality would be
nice.  
> I propose putting a configuration option: something like
> hbase.hstore.min.locality.to.skip.major.compact [between 0 and 1]
> such that you can decide whether or not to skip major compaction for an old region with
a single store file.
> I'll attach a patch, let me know what you guys think.
