A CLI for Amazon Athena, powered by JRuby.
Amazon Athena allows you to define a schema and query structured data in S3 without the usual Extract-Transform-Load process. This project uses the JDBC driver and JRuby to bring Athena access to your terminal.
Make sure you have JRuby >= 188.8.131.52.
Install from Rubygems:
gem install athena-cli
Setting up AWS credentials
The app will look for your AWS key and secret in the
AWS_SECRET_KEY environment variables. If you use multiple AWS accounts, awsam makes that a snap. Otherwise, you'll need to supply your AWS key and secret on every command via
Configuring the JDBC driver
The underlying Java code needs to know where to find your JDBC
driver. Add the path to your
CLASSPATH environment variable. Something like:
Setting the scratch folder
Athena requires an S3 scratch folder for storing results. You'll need to set the
ATHENA_S3_STAGING_DIR environment variable or pass via the
--staging-dir command line flag.
Check your settings
If you're calling it outside the repository folder, you'll want to drop a log4j.xml file into that folder to silence the logger.
