Upgrading the Big Data Protector

Starting from version 10.1, the Big Data Protector provides a feature to seamlessly move to a newer version. This uprade mechanism leverages the Rolling Restart feature provided by Cloudera.

Rolling Restart in Cloudera is a feature that allows services and role instances in a cluster to be restarted sequentially, rather than all at once. This minimizes downtime and ensures high availability during configuration changes or upgrades. By restarting components in controlled batches, Cloudera helps maintain cluster stability and service continuity without disrupting critical workloads.
