Xiang Li updated HBASE-17254:
-----------------------------
Description: In KeyValue (and maybe other ExtendedCell implementations),
heapOverhead() does not do alignment(padding gap). I think alignment is
required when calculating heapOverhead, because the space losses due to
alignment can not be used by other objects in heap. (was: In KeyValue(and
there might be other ExtendedCell implementations), heapOverhead() does not do
alignment(padding gap). I think alignment is required when calculating
heapOverhead, because the space losses due to alignment can not be used by
other objects in heap.)
> Do alignment in heapOverhead() for ExtendedCell implementations
