Flink Zookeeper leader change

Question

We are using flink version 1.9.1 and in a long-running environment, we encountered the specific issue mentioned in : https://issues.apache.org/jira/browse/FLINK-14091

While we are working on upgrading our version,

1. Why does zookeeper go for a leader change? As far as we checked, there was not scaling in our cluster at all. The load was very minimal. Is there any reason for the zookeeper leader change to happen?
2. After we upgrade our version, is there a way to replicate the zookeeper leader change manually?
