From 0 to 1: The Oozie Orchestration Framework

Prerequisites: Working with Oozie requires some basic knowledge of the Hadoop eco-system and running MapReduce jobs

Taught by a team which includes 2 Stanford-educated ex-Googlers and 2 ex-Flipkart Lead Analysts. This team has decades of practical experience in working with large-scale data processing jobs.

Oozie is like the formidable yet super-efficient admin assistant who can get things done for you if you know how to ask

Let's parse that

formidable yet super-efficient: Oozie is formidable because it is entirely written in XML which is hard to debug when things go wrong. However once you've figured out how to work with it it's like magic. Complex dependencies managing a multitude of jobs at different time schedules managing entire data pipelines are all made easy with Oozie

get things done for you: Oozie allows you to manage Hadoop jobs as well as Java programs scripts and any other executable with the same basic set up. It manages your dependencies cleanly and logically.

if you know how to ask: Knowing the right configurations parameters which gets the job done that is the key to mastering Oozie

What's Covered:

Workflow Management: Workflow specifications Action nodes Control nodes Global configuration real examples with MapReduce and Shell actions which you can run and tweak

Time-based and data-based triggers for Workflows: Coordinator specification Mimicing simple cron jobs specifying time and data availability triggers for Workflows dealing with backlog running time-triggered and data-triggered coordinator actions

Data Pipelines using Bundles: Bundle specification the kick-off time for bundles running a bundle on Oozie

Using discussion forums

Please use the discussion forums on this course to engage with other students and to help each other out. Unfortunately much as we would like to it is not possible for us at Loonycorn to respond to individual questions from students:-(

We're super small and self-funded with only 2 people developing technical video content. Our mission is to make high-quality courses available at super low prices.

The only way to keep our prices this low is to NOT offer additional technical support over email or in-person. The truth is direct support is hugely expensive and just does not scale.

We understand that this is not ideal and that a lot of students might benefit from this additional support. Hiring resources for additional support would make our offering much more expensive thus defeating our original purpose.

It is a hard trade-off.

Thank you for your patience and understanding!
