ZooKeeper sometimes fails to boot with NullPointerException #925

Open madejejej opened 1 year ago

madejejej commented 1 year ago

We're using the cp-zookeeper Docker image in our CircleCI specs with the default configuration and we only override the following env vars:

    environment:
      ZOOKEEPER_CLIENT_PORT: "2181"
      ZOOKEEPER_TICK_TIME: "2000"

In some cases, ZooKeeper fails to start with a NullPointerException. We're now on version 7.0.6, but we've also seen this behavior on 6.0.0, 6.2.0, and possibly older versions too.
