Description

This has been reported before. I am running mvn test on an AWS c4.2xlarge, Flink HEAD (version 69f7f6d9...) and seeing the missing curator classes. For example,

testMultipleLeaders(org.apache.flink.runtime.leaderelection.ZooKeeperLeaderElectionTest)  Time elapsed: 1.042 sec  <<< ERROR!
java.lang.NoClassDefFoundError: org/apache/curator/RetryPolicy
	at java.net.URLClassLoader.findClass(URLClassLoader.java:381)

	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
	at org.apache.flink.runtime.leaderelection.ZooKeeperLeaderElectionTest.testMultipleLeaders(ZooKeeperLeaderElectionTest.java:291)

The issue is resolved when removing the curator excludes from flink-runtime/pom.xml:

                                        <classpathDependencyExcludes>
                                                <classpathDependencyExclude>org.apache.curator:curator-recipes</classpathDependencyExclude>
                                                <classpathDependencyExclude>org.apache.curator:curator-client</classpathDependencyExclude>
                                                <classpathDependencyExclude>org.apache.curator:curator-framework</classpathDependencyExclude>
                                        </classpathDependencyExcludes>
