> While working on a patch for HBASE-2375, I came across a few bugs in the
> existing code related to splits.
> If a user triggers a manual split, it flips a forceSplit boolean to true and
> then triggers a compaction (this is very similar to my current implementation
> for HBASE-2375). However, the forceSplit boolean is flipped back to false at
> the beginning of Store.compact(). So the force split only acts on the first
> family in the table. If that Store is not splittable for some reason (it is
> empty or has only one row), then the entire region will not be split,
> regardless of what is in other families.
> Even if there is data in the first family, the midKey is determined based
> solely on that family. If it has two rows and the next family has 1M rows,
> we pick the split key based on the two rows.
