Rajeshbabu Chintaguntla updated HBASE-27667:
--------------------------------------------
Description:
Normalizer can be used to merge the regions which become emtpy post TTL expiry.
But it's picking the presplit regions as well. We can skip picking presplit
regions while preparing the merge plans by looking at the number of storefiles
instead of size. Presplit regions have zero storefiles where as the TTL expired
regions have 1 storefile with zero size.
