### Motivation When upgrading bookkeeper, you need to restart the bookie nodes in turn. When restarting a bookie, the pulsar will fail to read and write to the bookie, so as to isolate the bookie node. The default isolation is 30 minutes. With more and more restarted bookie nodes, the traffic of the whole cluster will be transferred to the remaining few bookie nodes, At this time, the bookie node may be abnormal due to excessive pressure, such as pulsar read-write timeout. ### Changes Therefore, I provide a configuration to dynamically turn off the health check. When upgrading bookkeeper, turn off the isolation function and turn it on after the upgrade, so as to avoid the impact of upgrading bookkeeper on the stability of pulsar. -- This is an automated message from the Apache Git Service.
