Engineering Updates

Computers can be weird sometimes, and there are few people who appreciate the depth of that weirdness more than we do. Sometimes, for example, your application cluster may get into a pattern where application masters are being taken over repeatedly, and you really want to know why. To help expose that extra level of debugging, we have released an optional feature into GA: application master takeover preference.

App Master Takeover

If your application master keeps going on vacation without leaving a note saying why, this is the feature for you. When a takeover occurs, the old application master will be saved as a utility instance that is not serving any traffic, so you can SSH into the box and investigate what is up with its shoddy work ethic. As always, if you need extra help, you can always open a ticket with our support team too!

Utility Instances

This feature is intended only for that extra level of debugging, and is not recommended as a default configuration.

A bunch of other updates are chronicled in our regular release notes!
