14. The master node login, create a new file on a local file called hbasetest.txt, compiles the content, requires a new table 'test', the column group of 'cf', then this bulk insert data table, the data as shown below :
'ROW1', 'CF2: A', 'VALUE1'
'ROW2', 'CF2: B', 'value2'
'Row3', 'CF2: C', 'value3'
