binlijin commented on HBASE-22433:
----------------------------------
After HBASE-22447/HBASE-22441 we need to make a decision to whether to support
override an already cached block. If we need to support we need to make sure
there is no ref to the old cached block before override it, HBASE-20789 have no
check and just override, so have bugs... If there is ref to the old cached
block we need to give up the override, or do complicated works to release the
old cached blocks when there is no ref.
