Problem running examples in hama

Hi,

      I compiled the latest hama-trunk version with the newest version of
hbase(0.20.4) and zookeeper lib files and when I run the examples
$hama-home/bin/hama examples rand 20 20 20% tmp I got class not found
exception
Exception in thread "main" java.lang.
NoClassDefFoundError: examples
Caused by: java.lang.ClassNotFoundException: examples
       at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
       at java.security.AccessController.doPrivileged(Native Method)
       at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
       at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
       at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
       at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: examples.  Program will exit.

Could you please help me on this. I am using hbase and hama for the first
time.

Thanks
Peeyush

Hello,

Please try to run the following command: # bin/hama
org.apache.hama.examples.ExampleDriver

I'll add example launcher command to run script soon.

Thanks!
