Anoop Sam John commented on HBASE-14921:
----------------------------------------
So we are having 2 sets of MSLAB chunks. The 3 ints per cell also written to
chunks we get from same MSLAB. We need this really? So if we change to 8
bytes per cell, and when chunk size is 2 MB, we can have 262144 cells. We will
have this many really? If not, we may waste that chunk? Pros and cons. let me
think more on that.
