ODP Rolling Upgrade

Note

The Rolling Upgrade is not supported from ODP 3.2.x.x to 3.3.6.x-x release.

The rolling upgrades are not supported in ODP 3.3.6.0-1 due to the migration to Java 11. This release mandates that all components run on a unified Java version, and during a rolling upgrade, it is challenging to maintain consistency across the stack. Since Ambari manages the Java environment for all components, transitioning to Java 11 requires all components to operate on the same Java version. The rolling upgrades, which typically stagger component upgrades, would lead to compatibility issues if some components are still using an older Java version. To ensure stability and consistency, a full upgrade is necessary.
