Daisuke Kobayashi commented on HBASE-13052:
-------------------------------------------
Thanks [~misty]! Just a quick confirmation for ConstantSizeRegionSplitPolicy.
bq. the default split policy in HBase 0.94 and earlier. Split regions based
only upon the size of the store file.
This was the default until 0.92, right?
