Anoop Sam John commented on HBASE-16438:
----------------------------------------
We were never doing this way of writing seqId bytes onto MSLAB chunks (Data
chunks).. we keep it as state. And FYI, when we flush cells to HFiles, then
also we write seqId but as a VLong.
> Create a cell type so that chunk id is embedded in it

> For CellChunkMap we may need a cell such that the chunk out of which it was
> created, the id of the chunk be embedded in it so that when doing flattening
> we can use the chunk id as a meta data. More details will follow once the
> initial tasks are completed.
> Why we need to embed the chunkid in the Cell is described by [~anastas] in
> this remark over in parent issue
