OozieZombie

This project should help with some of the oozie pains you might run into. When you have close to a thousand coordinators running and you have a problem on the cluster the last thing you want to do is manually triggering a retry.

But perhaps this will more serve as an example on how to use the oozie rest service for whatever needs you have.

For now this isn't incredibly modular/generic and might drastically change.

Main services

FailedActionsRerun

• Look at each running coordinator and it's actions and decide to rerun them based on some criteria.
• Look at constantly failing coordinators and after some time decide to suspend them.

SuspendedCoordinatorKill

Look at suspended coordinators and if they have been suspended for x days kill them.

Build

Prerequisite

Java 1.7+ Maven 3.2+

How to create a jar

mvn package spring-boot:repackage

You now have a jar in the target dir which you can directly use:

java -jar target/OozieZombie-<version>.jar

Start it like a deamon on the cli as your own user

nohup java -Xmx64m -jar OozieZombie-<version>.jar &

If you want to make some config changes on the machine you run this on create a file called application.properties and add properties there.
