Description

in OS Flink, flink relocate zk to org.apache.flink.shaded.zookeeper3.org.apache.zookeeper.*

https://github.com/apache/flink-shaded/blob/82f8bb3324864491dc62c4d3e27f1c1ccc49ac84/flink-shaded-zookeeper-parent/pom.xml#L68

the maven-shade-plugin changes all 'org.apache.zookeeper' to 'org.apache.flink.shaded.zookeeper3.org.apache.zookeeper'

if JVM has -Dzookeeper.clientCnxnSocket=org.apache.zookeeper.*, and in shaded zk jar, will get NoSunchMethodException
