presplitting regions

[Mohamed Ghareb]

Kindly when I create new tables with presplitting region,
I need to use the firstrow & lastrow argument, my question if my key is number 
"integer" can I put start & end row with decimal number or I need to convert it 
to hexadecimal number
hbase org.apache.hadoop.hbase.util.RegionSplitter tablename HexStringSplit 
--firstrow 9990 --lastrow 3000000 -c 5
