Shaofeng SHI commented on KYLIN-965:
------------------------------------

Extract these values to kylin.properties like this:

{code}
# Region cut size for SMALL, MEDIUM and LARGE cubes, in GB
kylin.hbase.region.size.small=10
kylin.hbase.region.size.medium=20
kylin.hbase.region.size.large=100

# Max region count when create HTable
kylin.hbase.region.max.count=500
{code}

> Kylin hardcoded the region split size in RangeKeyDistributionReducer.java; It will use 10G, 20G and 100G as the split for a Small/Medium/Large cube; Besides, it set a limit on max region count to 500; Hardcode is not good; we should externalize these values to config file.
