Description: # Apiarist
        
        A python 2.5+ package for defining Hive queries which can be run on AWS EMR.
        
        It is, in its current form, only addressing a very narrow use-case. 
        Reading large CSV files into a Hive database, running a Hive query, and outputting the results to a CSV file.
        
        Future versions will endeavour to extend the input/output formats and be runnable locally.
        
        It is modeled on [mrjob](https://github.com/Yelp/mrjob) and attempts to present a similar API and use similar common variables to cooperate with `boto`.
        
        ## A simple Hive job
        
        You will need to provide four methods: 
        
          - `table()` the name of the table that your query will select from.
          - `input_columns()` the columns in the source data file.
          - `output_columns()` the columns that your query will output.
          - `query` the HiveQL query.
        
        This code lives in `/examples`.
        
        ```python
        from apiarist.job import HiveJob
        
        class EmailRecipientsSummary(HiveJob):
        
            def table(self):
                return 'emails_sent'
        
            def input_columns(self):
                return [
                        ('day', 'STRING'),
                        ('weekday', 'INT'),
                        ('sent', 'BIGINT')
                        ]
        
            def output_columns(self):
                return [
                        ('year', 'INT'),
                        ('weekday', 'INT'),
                        ('sent', 'BIGINT')
                        ]
        
            def query(self):
                return "SELECT YEAR(day), weekday, SUM(sent) FROM emails_sent GROUP BY YEAR(day), weekday;"
        
        if __name__ == "__main__":
            EmailRecipientsSummary().run()
        ```
        
        ## Try it out
        
        EMR:
        
            python email_recipients_summary.py s3://path/to/your/file.csv
