> This happens in processDeadServersAndRegionsInTransition() on Master startup.
> RegionAssigments is a tree map and TreeMap.clone() is expensive as it builds
> a tree from sorted data (Order of n). There were a million entries in
> RegionAssigments and from jstack, thread was stuck in
> TreeMap.buildFromSorted() for couple of hours.
> Instead of this shadow clone, wrapping as an unmodifiable Map should be
> enough.
