 SPLITS role is to create a table , it will default to the table of the N Region 
 examples according to the official website [ '01 ', '02 ', '03 ', '04' ] , table t1 will be created when the sub- 5 region, RowKEY by lexicographical partition 
 Rowkey less than " 01" , assigned to the region1 
 Rowkey greater than equal to " 01" is less than "02" , assigned to the region2 
 Rowkey greater than equal to " 02" is less than "03" , assigned region3 
 Rowkey greater than equal to " 03 " is less than "04" , assigned region4 
 Rowkey greater than equal to " 04" , assigned region5  
 Assuming execute the following command 
 put 't1', '00101 ',' f1: c1 ',' hello ' 
 put 't1', '00201 ',' f1: c1 ',' hello ' 
 put 't1', '01101 ',' f1: c1 ',' hello ' 
 put 't1', '02101 ',' f1: c1 ',' hello ' 
 put 't1', '02201 ',' f1: c1 ',' hello ' 
 put 't1', '03101 ',' f1: c1 ',' hello ' 
 put 't1', '03201 ',' f1: c1 ',' hello ' 
 put 't1', '04101 ',' f1: c1 ',' hello ' 
 00101 and 00201 will be assigned region1, because lexicographical 
 00  101 and  00  201 's  left (2)  is less than "  01  ", pay attention to see bold , and so on 
 01101 assigned region2 
 02101 and 02201 assigned region3 
 03101 and 03201 assigned region4 
 04101 assigned region5
