Hi, I am testing out Cassandra 1.2 on two of my local servers. But I face problems with assigning tokens to my nodes. When I use nodetool to set token, I end up getting an java Exception. My test setup is as follows, Node1: <local ip 1> (seed) Node2: <local ip 2> (seed)
Since I have two nodes, i calculated the tokens as 0 and 2^127/2 = 85070591730234615865843651857942052864. I was able to set token 0 for my first node using nodetool move 0 , but when i am trying to set 85070591730234615865843651857942052864 for my second node, it throws a main UndeclaredThrowableException. Full stack is attached bellow. user@server~$ nodetool move 85070591730234615865843651857942052864 Exception in thread "main" java.lang.reflect.UndeclaredThrowableException at $Proxy0.getTokenToEndpointMap(Unknown Source) at org.apache.cassandra.tools.NodeProbe.getTokenToEndpointMap(NodeProbe.java:288) at org.apache.cassandra.tools.NodeCmd.printRing(NodeCmd.java:215) at org.apache.cassandra.tools.NodeCmd.main(NodeCmd.java:1051) Caused by: javax.management.InstanceNotFoundException: org.apache.cassandra.db:type=StorageService at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getMBean(DefaultMBeanServerInterceptor.java:1095) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.getAttribute(DefaultMBeanServerInterceptor.java:643) at com.sun.jmx.mbeanserver.JmxMBeanServer.getAttribute(JmxMBeanServer.java:668) at javax.management.remote.rmi.RMIConnectionImpl.doOperation(RMIConnectionImpl.java:1463) at javax.management.remote.rmi.RMIConnectionImpl.access$300(RMIConnectionImpl.java:96) at javax.management.remote.rmi.RMIConnectionImpl$PrivilegedOperation.run(RMIConnectionImpl.java:1327) at javax.management.remote.rmi.RMIConnectionImpl.doPrivilegedOperation(RMIConnectionImpl.java:1419) at javax.management.remote.rmi.RMIConnectionImpl.getAttribute(RMIConnectionImpl.java:656) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:322) at sun.rmi.transport.Transport$1.run(Transport.java:177) at sun.rmi.transport.Transport$1.run(Transport.java:174) at java.security.AccessController.doPrivileged(Native Method) at sun.rmi.transport.Transport.serviceCall(Transport.java:173) at sun.rmi.transport.tcp.TCPTransport.handleMessages(TCPTransport.java:553) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run0(TCPTransport.java:808) at sun.rmi.transport.tcp.TCPTransport$ConnectionHandler.run(TCPTransport.java:667) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:722) at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:273) at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:251) at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:160) at com.sun.jmx.remote.internal.PRef.invoke(Unknown Source) at javax.management.remote.rmi.RMIConnectionImpl_Stub.getAttribute(Unknown Source) at javax.management.remote.rmi.RMIConnector$RemoteMBeanServerConnection.getAttribute(RMIConnector.java:901) at javax.management.MBeanServerInvocationHandler.invoke(MBeanServerInvocationHandler.java:280) Any suggestions towards solving this problem would be deeply appreciated. thanks, rahul -- Rahul Erai www.cse.iitk.ac.in/~rahule
