I'm new to java and trying to run a MR that uses HIPI: http://hipi.cs.virginia.edu/ I've used the command as described in: http://hadoop.apache.org/common/docs/r0.20.2/mapred_tutorial.html I'm using hadoop 0.20.2
my command looks like: hadoop jar grayscalefromfile_exc.jar grayscalefromfile_exc.StubDriver -libjars hipi-0.0.1.jar imgs imgsOut1
where the path looks like:
--
--grayscalefromfile_exc.jar
--hipi-0.0.1.jar
The error i get: Exception in thread "main" java.lang.NoClassDefFoundError: hipi/imagebundle/mapreduce/ImageBundleInputFormat at grayscalefromfile_exc.StubDriver.run(StubDriver.java:89) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79) at grayscalefromfile_exc.StubDriver.main(StubDriver.java:103) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.RunJar.main(RunJar.java:186) Caused by: java.lang.ClassNotFoundException: hipi.imagebundle.mapreduce.ImageBundleInputFormat at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 9 more
Needless to say , the hipi-0.0.1.jar, has the path inside: hipi/imagebundle/mapreduce/ImageBundleInputFormat.java
Tnx
