truncate_preserve should get table split keys as it is instead of converting them to string type and then again to bytes

    Description

      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.

            h_table = org.apache.hadoop.hbase.client.HTable.new(conf, table_name)
      splits = h_table.getRegionLocations().keys().map{|i| i.getStartKey} :byte
      splits = org.apache.hadoop.hbase.util.Bytes.toByteArrays(splits)

      Truncating 'emp3' table (it may take a while):
 - Disabling table...
 - Dropping table...
 - Creating table with region boundaries...

ERROR: java.lang.IllegalArgumentException: All split keys must be unique, found duplicate: B\x11S\xEF\xBF\xBD\xEF\xBF\xBD\xEF\xBF\xBD\x00\x00, B\x11S\xEF\xBF\xBD\xEF\xBF\xBD\xEF\xBF\xBD\x00\x00
