    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

    This exception normally means you either have to add the said class to your dependencies or you miswrote it. Look in the documentation of your library how to add it as a dependency.
  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>

    This was caused by a failure to instantiate Kafka broker. Check your dependencies.
