Hi, all I'm attempting to invoke the gridmix2 benchmark on hadoop-0.20.2, I have modify the environment variables in the scripts accordingly, but after I typed "sh rungridmix_2" , the system gives an error like following:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/streaming/StreamJob at org.apache.hadoop.mapred.GridMixRunner$GridMixJob$1.addJob(Unknown Source) at org.apache.hadoop.mapred.GridMixRunner.addJobs(Unknown Source) at org.apache.hadoop.mapred.GridMixRunner.addAllJobs(Unknown Source) at org.apache.hadoop.mapred.GridMixRunner.addjobs(Unknown Source) at org.apache.hadoop.mapred.GridMixRunner.main(Unknown Source) 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:616) at org.apache.hadoop.util.RunJar.main(RunJar.java:156) Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.streaming.StreamJob at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:319) at java.lang.ClassLoader.loadClass(ClassLoader.java:264) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:332) ... 10 more I checked the hadoop-0.20.2-streaming.jar, it's there and it seems to be in a healthy status ( I just upload it to the cluster from my laptop where the gridmix2 has run successfully ) Anyone once met such a problem? Thank you very much! Nan
