Description

After building successfully I was trying to run the ZooKeeperServerMain class with the zoo_sample.cfg and getting the following exception:

Exception in thread "main" java.lang.NoClassDefFoundError: com/codahale/metrics/ReservoirException in thread "main" java.lang.NoClassDefFoundError: com/codahale/metrics/Reservoir at org.apache.zookeeper.metrics.impl.DefaultMetricsProvider$DefaultMetricsContext.lambda$getSummary$2(DefaultMetricsProvider.java:126) at java.util.concurrent.ConcurrentHashMap.computeIfAbsent(ConcurrentHashMap.java:1660) at org.apache.zookeeper.metrics.impl.DefaultMetricsProvider$DefaultMetricsContext.getSummary(DefaultMetricsProvider.java:122) at org.apache.zookeeper.server.ServerMetrics.<init>(ServerMetrics.java:74) at org.apache.zookeeper.server.ServerMetrics.<clinit>(ServerMetrics.java:44) at org.apache.zookeeper.server.ZooKeeperServerMain.runFromConfig(ZooKeeperServerMain.java:132) at org.apache.zookeeper.server.ZooKeeperServerMain.initializeAndRun(ZooKeeperServerMain.java:112) at org.apache.zookeeper.server.ZooKeeperServerMain.main(ZooKeeperServerMain.java:67)Caused by: java.lang.ClassNotFoundException: com.codahale.metrics.Reservoir at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 8 more

Can anyone guide on how to rectify this, it uses 

<dropwizard.version>3.2.5</dropwizard.version> not the 4.x
