Hello,
I'm using oozie 4.2.0 on a HA cluster, I got a launcher exception when I run the oozie example app hive2: 2016-09-09 10:10:44,927 WARN Hive2ActionExecutor:523 - SERVER[emr-header-1.cluster-500031470] USER[oozie] GROUP[-] TOKEN[] APP[hive2-wf] JOB[0000004-160908174647725-oozie-oozi-W] ACTION[0000004-160908174647725-oozie-oozi-W@hive2-node] Launcher ERROR, reason: Main class [org.apache.oozie.action.hadoop.Hive2Main], main() threw exception, org/apache/hadoop/hive/conf/HiveConf 2016-09-09 10:10:44,931 WARN Hive2ActionExecutor:523 - SERVER[emr-header-1.cluster-500031470] USER[oozie] GROUP[-] TOKEN[] APP[hive2-wf] JOB[0000004-160908174647725-oozie-oozi-W] ACTION[0000004-160908174647725-oozie-oozi-W@hive2-node] Launcher exception: org/apache/hadoop/hive/conf/HiveConf java.lang.NoClassDefFoundError: org/apache/hadoop/hive/conf/HiveConf at org.apache.oozie.action.hadoop.Hive2Main.runBeeline(Hive2Main.java:240) at org.apache.oozie.action.hadoop.Hive2Main.run(Hive2Main.java:223) at org.apache.oozie.action.hadoop.LauncherMain.run(LauncherMain.java:47) at org.apache.oozie.action.hadoop.Hive2Main.main(Hive2Main.java:56) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.oozie.action.hadoop.LauncherMapper.map(LauncherMapper.java:236) at org.apache.hadoop.mapred.MapRunner.run(MapRunner.java:54) at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:453) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:343) at org.apache.hadoop.mapred.LocalContainerLauncher$EventHandler.runSubtask(LocalContainerLauncher.java:380) at org.apache.hadoop.mapred.LocalContainerLauncher$EventHandler.runTask(LocalContainerLauncher.java:301) at org.apache.hadoop.mapred.LocalContainerLauncher$EventHandler.access$200(LocalContainerLauncher.java:187) at org.apache.hadoop.mapred.LocalContainerLauncher$EventHandler$1.run(LocalContainerLauncher.java:230) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hive.conf.HiveConf at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 21 more job definition: <?xml version="1.0" encoding="UTF-8"?> <!-- Licensed to the Apache Software Foundation (ASF) under one or more contributor license agreements.
