I'm using HBase 1.4.4 (AWS/EMR) and I'm looking for an automated
solution because I believe there are going to be a few hundred if not
thousand merges. It's also challenging to find candidate pairs.

Hi Austin,
Which version are you using? Why not just using the shell merge command?

We're currently sitting at a very high number of regions due to an
initially poor value for hbase.regionserver.regionSplitLimit and would
like to reign in our region count. Additionally, we have a
spatio-temporal key structure and our region pre-splitting was done
evenly, without regard to the spatial distribution of our data and thus
have a lot of small and empty regions we'd like to clean up. I've found
the HMerge class [1], and it seems it would do something reasonable for
our used case. However, it's marked as Private and doesn't seem to be
used anywhere so I thought I'd ask if anyone knows the status of this
class and how safe it is.
Thanks,
Austin
