Anastasia Braginsky commented on HBASE-18010:
---------------------------------------------
Thanks [~ramkrishna], I understand that you would like to clean mapping of the
chunks no longer in use. But what do you say about the following scenario:
1. Chunk C was allocated and got ID 5
2. C was reclaimed and removed from mapping, but was returned to pool still
holding ID 5
3. C was reused from pool and returned to the user once again
4. Cell residing on C is asked what is its chunk id and 5 is the answer
5. ChunkCreator is asked to translate chunk ID 5, but returns null...
Am I wrong?
> Connect CellChunkMap to be used for flattening in CompactingMemStore

> The CellChunkMap helps to create a new type of ImmutableSegment, where the
> index (CellSet's delegatee) is going to be CellChunkMap. No big cells or
> upserted cells are going to be supported here.
