Walk through some of the best practices to keep in mind when it comes to upgrading your cluster, and learn how to leverage new Upgrade Wizard features in Cloudera Enterprise 5.3.
For most mission critical workloads, downtime is never an option. Any downtime can have a direct impact on revenue and lead to frantic calls in the middle of the night. For this reason, upgrading the software that powers these workloads can often be a daunting task. It can cause unpredictable issues without access to support. That’s why an enterprise-grade administration tool is crucial for running Hadoop in production. Hadoop consists of dozens of components, running across multiple machines, all with their own configurations. That can lead to a lot of complexity and uncertainty - especially when taking the upgrade plunge.
Cloudera Manager makes it easy and is the only production-ready administration tool for Hadoop. Not only does Cloudera Manager feature zero-downtime rolling upgrades, but it also has a built in Upgrade Wizard to make upgrades simple and predictable.
