Tanuj Khurana updated PHOENIX-7612:
-----------------------------------
    Description: IndexRegionObserver maintains an in memory state to correctly 
generate mutations for concurrent updates to the same row. These mutations hold 
references to cells which can be backed by off-heap memory. It is not safe to 
access these cells later as that memory can be reclaimed or reused. The copy 
constructor of the Mutation class doesn't copy the cells.
