> If we take int,long or double bytes as split keys then we are not creating table with same split keys because converting them to strings directly and to bytes is giving different split keys, sometimes getting IllegalArgument exception because of same split keys(converted). Instead we can get split keys directly from HTable and pass them while creating table.

>       splits = h_table.getRegionLocations().keys().map{|i| i.getStartKey} :byte
>       splits = org.apache.hadoop.hbase.util.Bytes.toByteArrays(splits)
