Xavier Léauté b517c3339b remove ZooKeeper 3.4 support + pass tests with Java 15 (#11073) ... With this change, Druid will only support ZooKeeper 3.5.x and later. In order to support Java 15 we need to switch to ZK 3.5.x client libraries and drop support for ZK 3.4.x (see #10780 for the detailed reasons) * remove ZooKeeper 3.4.x compatibility * exclude additional ZK 3.5.x netty dependencies to ensure we use our version * keep ZooKeeper version used for integration tests in sync with client library version * remove the need to specify ZK version at runtime for docker * add support to run integration tests with JDK 15 * build and run unit tests with Java 15 in travis		2021-05-25 12:49:49 -07:00
