Enis Soztutar commented on HBASE-15065:
---------------------------------------
Thanks Ted for working on this. This approach looks more realistic and useful
for the general case.
A couple of questions:
- Do we have to support the old RegionNormalizer interface? Sorry I did not
check whether it is a client-public interface or not.
- Executing the region normalization plans is serial. If we end up with
hundreds of plans, will this become a bottleneck?
- Why sort the splits plans before merge plans for execution?
[~mantonov] what do you think?
> SimpleRegionNormalizer should return multiple normalization plans in one run
