I managed to set it up and run it on hadoop. However, I am facing problems when I try to execute DisplayCanopy program on hadoop. I get following error: Running on hadoop, using HADOOP_HOME=/usr/local/hadoop No HADOOP_CONF_DIR set, using /usr/local/hadoop/conf 11/02/21 04:00:11 WARN driver.MahoutDriver: No org.apache.mahout.clustering.display.DisplayCanopy.props found on classpath, will use command-line arguments only Exception in thread "main" java.lang.IllegalAccessException: Class org.apache.hadoop.util.ProgramDriver$ProgramDescription can not access a member of class org.apache.mahout.clustering.display.DisplayCanopy with modifiers "public static" at sun.reflect.Reflection.ensureMemberAccess(Reflection.java:65) at java.lang.reflect.Method.invoke(Method.java:588) at org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver.java:68) at org.apache.hadoop.util.ProgramDriver.driver(ProgramDriver.java:139) at org.apache.mahout.driver.MahoutDriver.main(MahoutDriver.java:184) 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:156) At command prompt, I give the following command: /usr/local/mahout-distribution-0.4/bin/mahout org.apache.mahout.clustering.display.DisplayCanopy I have set all relevant environment variables.
