Hi everybody, I have a question about shutting down a LocalCluster.
This is my test environment : - Windows 7 SP1 - Apache Storm 1.0.3 - Java 1.8.0_111 - Eclipse Mars.2 (4.5.2) I'm running a simple topology using LocalCluster without any particular configuration. The problem appears after I kill the topology using *LocalCluster::killTopology(String arg0)*. After that, I stop the local cluster using *LocalCluster::shutdown()*, then I have this ugly stack trace. * 2017-11-20 16:52:04,993 ERROR o.a.s.d.s.ReadClusterState:181 - Failed to Sync Supervisor java.lang.RuntimeException: java.lang.InterruptedException* at org.apache.storm.utils.Utils.wrapInRuntime(Utils.java:1507) at org.apache.storm.zookeeper.Zookeeper.getChildren(Zookeeper.java:260) at org.apache.storm.cluster.ZKStateStorage.get_children(ZKStateStorage.java:174) at org.apache.storm.cluster.StormClusterStateImpl.assignments(StormClusterStateImpl.java:153) at org.apache.storm.daemon.supervisor.ReadClusterState.run(ReadClusterState.java:126) at org.apache.storm.event.EventManagerImp$1.run(EventManagerImp.java:54) *Caused by: java.lang.InterruptedException* at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:502) at org.apache.storm.shade.org.apache.zookeeper.ClientCnxn.submitRequest(ClientCnxn.java:1342) at org.apache.storm.shade.org.apache.zookeeper.ZooKeeper.getChildren(ZooKeeper.java:1588) at org.apache.storm.shade.org.apache.zookeeper.ZooKeeper.getChildren(ZooKeeper.java:1625) at org.apache.storm.shade.org.apache.curator.framework.imps.GetChildrenBuilderImpl$3.call(GetChildrenBuilderImpl.java:210) at org.apache.storm.shade.org.apache.curator.framework.imps.GetChildrenBuilderImpl$3.call(GetChildrenBuilderImpl.java:203) at org.apache.storm.shade.org.apache.curator.RetryLoop.callWithRetry(RetryLoop.java:108) at org.apache.storm.shade.org.apache.curator.framework.imps.GetChildrenBuilderImpl.pathInForeground(GetChildrenBuilderImpl.java:200) at org.apache.storm.shade.org.apache.curator.framework.imps.GetChildrenBuilderImpl.forPath(GetChildrenBuilderImpl.java:191) at org.apache.storm.shade.org.apache.curator.framework.imps.GetChildrenBuilderImpl.forPath(GetChildrenBuilderImpl.java:38) at org.apache.storm.zookeeper.Zookeeper.getChildren(Zookeeper.java:255) ... 4 more Does anybody knows what can be the source of this problem ? Maybe this is the normal behavior, I just want to know. Thanks ! Regards, Robin *PS *: I found someone that have exactly the same problem on Stackoverflow if it can help understand the problem ( https://stackoverflow.com/questions/45176886/error-running-storm-topology-locally/47396504 ).
