Graceful shutdown

You can configure the graceful shutdown as described in Graceful shutdown.


As a default, ZooKeeper servers have 2 minutes to shut down gracefully.

The ZooKeeper server process will receive a SIGTERM signal when Kubernetes wants to terminate the Pod. After the graceful shutdown timeout runs out, and the process still didn’t exit, Kubernetes will issue a SIGKILL signal.

This is equivalent to executing the bin/ stop command, which internally executes kill <zookeeper-pid> (code).

However, there is no acknowledge message in the log indicating a graceful shutdown.
