DISCLAIMER: This is a method that is not recommended for any production use, only for development purposes. Only Cloudbreak official versions are supported, and upgrading to a non-supported version could cause unforeseen issues, and loss of official Hortonworks support. Moreover, this method only works for upgrades, not downgrades; downgrades would result in data loss.
Recently, I have been playing with Cloudbreak and have been needing to upgrade my local version. While it follows the principles detailed in Hortonworks documentation, I thought I'd share a quick step by step guide on how to upgrade to any version of Cloudbreak.
