Review comment:
Seems like a good candidate for `final` and `setRegionInfo()` can be
removed?

Review comment:
By introducing `hashCode()` and `equals()`, comparison is no more
dependant on getter methods, can we also remove `getFirstRegion()` and
`getSecondRegion()`? Although they are useful, but I don't think they will be
used anymore. Thought?

Review comment:
Nice one, since we have two `final RegionInfo` and hopefully they are
not getting mutated after plan generation, we can do this.
