ApacheCon EU 2014

Cloudera Engineering has heavily incorporated Docker, an extension of Linux Containers, into our integration testing framework for Apache HBase, a distributed "NoSQL" datastore. Through the use of Docker images, we have succeeded in parameterizing the Apache Hadoop environment on which our tests are deployed. This allows us to test functionality and compatibility across a wider range of platforms in a much shorter amount of time, resulting in dramatic improvements in utilization of our computational resources. In this talk, we will present how we use Docker during test development to reduce the time it takes to write and run functional tests and to include more test configurations. We will then go in-depth on a particularly novel use case: compatibility testing. Attendees will come away with a perspective on Docker that will help them adopt it into their own test frameworks.
