    handleSplitRegionBoundaryFailureDuringInitialization will be true for 
scanning intermediate chunks in ChunkedResultIterator. When we create scanner 
for new chunk we might see stale region boundaries in that case also we need to 
forcibly recreate the iterator with new boundaries. In normal case if we get 
StaleRegionBoundary exception while creating scanner BaseResultIterator handles 
it.
