    I am getting the following error message when one of the steps in my reducer exceeds the in memory limit and has to spill records to a temp file. It appears this is because the jug-lgpl-2.0.0.jar is not included in the distributed cache deployment of Kettle in the Hadoop cluster. Work around is to manually add this JAR to the lib directory of Kettle in Hadoop's distributed cache. 2012/06/01 21:33:00 - Pentaho MapReduce - ERROR (version 4.3.0, build 1 from 2012-04-12 17.12.40 by buildguy) : [FAILED] -- Task: 3 Attempt: 2 Event: 48 2012/06/01 21:33:00 - Pentaho MapReduce - ERROR (version 4.3.0, build 1 from 2012-04-12 17.12.40 by buildguy) : Error: java.lang.ClassNotFoundException: org.safehaus.uuid.UUIDGenerator at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) at org.pentaho.di.core.util.UUIDUtil.<clinit>(UUIDUtil.java:53) at org.pentaho.di.core.vfs.KettleVFS.createTempFile(KettleVFS.java:353) at org.pentaho.di.trans.steps.sort.SortRows.sortExternalRows(SortRows.java:144) at org.pentaho.di.trans.steps.sort.SortRows.addBuffer(SortRows.java:127) at org.pentaho.di.trans.steps.sort.SortRows.processRow(SortRows.java:374) at org.pentaho.di.trans.SingleThreadedTransExecutor.oneIteration(SingleThreadedTransExecutor.java:342) at org.pentaho.hadoop.mapreduce.GenericTransReduce.reduce(GenericTransReduce.java:133) at org.pentaho.hadoop.m

    A few things cause this exception: 1) Check if you have all jars and if they're in the correct path when running. 2) Your classpath might be broken, you can define it in the command line with "java -cp yourClassPath" or at your IDE if you're using one.
  4. Speed up your debug routine!

    If you're using Hibernate, this indicates you're missing FasterXML Classmate dependency, which you can add with the following: <groupId>com.fasterxml</groupId> <artifactId>classmate</artifactId> <version>1.0</version>

    Check if you didn't forget to instantiate your topic in the kafka broker.
