Hadoop: Data Processing and Modelling

Time for action – setting up the employee database

No discussion of databases is complete without the example of an employee table, so we will follow tradition and start there.

1. Create a tab-separated file named employees.tsv with the following entries:

   Alice  Engineering  50000  2009-03-12
   BobSales  35000  2011-10-01
   Camille  Marketing  40000  2003-04-20
   David  Executive  75000  2001-03-20
   Erica  Support  34000  2011-07-07

2. Connect to the MySQL server:

   $ mysql -u hadoopuser -p hadooptest
   

3. Create the table:

   Mysql> create table employees(
   first_name varchar(10) primary key,
   dept varchar(15),
   salary int,
   start_date date
   ) ;
   

4. Load the data from the file into the database:

   mysql> load data local infile '/home/garry/employees.tsv'
       -> into table employees
    -> fields terminated ...
