> After HBASE-12295, we have block with MemoryType.SHARED or
> MemoryType.EXCLUSIVE, the block in offheap BucketCache will be shared, and
> have an reference count to track its life cycle. If no rpc reference to the
> shared block, then the block can be evicted.
> while after the HBASE-21916, we introduced an refcount for ByteBuff, then I
> think we can unify the two into one. tried to fix this when preparing patch
> for HBASE-21879, but seems can be different sub-task, and it won't affect the
> main logic of HBASE-21879, so create a seperate one.
