Hello, I’m new to Helix and trying to get a taste of running some examples. The closest model (to what I need) is the resync filestore recipe example.
The instructions look simple enough: git clone https://git-wip-us.apache.org/repos/asf/incubator-helix.git cd recipes/rsync-replicated-file-system/ mvn clean install package -DskipTests cd target/rsync-replicated-file-system-pkg/bin chmod +x * ./quickdemo However, I don’t think what I’ve got was a successful run. Besides the exceptions, the program hung there until I hit Ctrl-C. are there anythings I missed? What else do I need to get this recipe example to work? BTW, I’m running on Mac OS X 10.9.2. ./quickdemo.sh STARTING NODES localhost_12002 transitioning from OFFLINE to SLAVE for repository_0 localhost_12003 transitioning from OFFLINE to SLAVE for repository_0 No master found localhost_12003 transitioned from OFFLINE to SLAVE for repository_0 localhost_12001 transitioning from OFFLINE to SLAVE for repository_0 No master found localhost_12001 transitioned from OFFLINE to SLAVE for repository_0 No master found localhost_12002 transitioned from OFFLINE to SLAVE for repository_0 No master found No master found No master found localhost_12001 transitioning from SLAVE to MASTER for repository_0 0 [pool-7-thread-2] ERROR org.apache.helix.messaging.handling.HelixStateTransitionHandler - Exception while executing a state transition task repository_0 java.lang.reflect.InvocationTargetException 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:606) at org.apache.helix.messaging.handling.HelixStateTransitionHandler.invoke(HelixStateTransitionHandler.java:350) at org.apache.helix.messaging.handling.HelixStateTransitionHandler.handleMessage(HelixStateTransitionHandler.java:300) at org.apache.helix.messaging.handling.HelixTask.call(HelixTask.java:85) at org.apache.helix.messaging.handling.HelixTask.call(HelixTask.java:42) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) Caused by: java.lang.IllegalArgumentException: Path must start with / character at org.apache.helix.util.PathUtils.validatePath(PathUtils.java:51) at org.apache.helix.manager.zk.ZkCacheBaseDataAccessor.prependChroot(ZkCacheBaseDataAccessor.java:135) at org.apache.helix.manager.zk.ZkCacheBaseDataAccessor.update(ZkCacheBaseDataAccessor.java:270) at org.apache.helix.filestore.FileStoreStateModel.onBecomeMasterFromSlave(FileStoreStateModel.java:153) ... 12 more 9 [pool-7-thread-2] ERROR org.apache.helix.participant.statemachine.StateModel - Default rollback method invoked on error.
