Anoop Sam John commented on HBASE-19033:
----------------------------------------
ScanOptions -> I was thinking why to have this extra interface and this
object having ScanInfo. Why not pass ScanInf itself (cloned value). But then I
see it is IA private. ScanInfo is having some other states which also CP
user might want to change? Like keepDeletedCells? I dont know. Just asking.
But that is having certain things which is not to be exposed to CPs. So I
think ScanOptions interface way is ok. After all it is an interface type being
passed so we can add what new wanted with out any BC break any time. I think
this patch is coming good.
> Allow CP users to change versions and TTL before opening StoreScanner
