I have a maven project that contains 30 GroovyTestCase 'junit' test classes. I was able to generate the test-jar file that contains all the test classes, using http://maven.apache.org/guides/mini/guide-attached-tests.html . However, every time I try to run the jar file using the following command:
java -cp target/groovy-tests-1.0-SNAPSHOT-tests.jar com.mycompany.TestClass
I get the following error:

I have been struggling to find a way to generate the jar file so I can run all tests without the maven project.
Please let me know if there is another way to generate the jar file...

Seems Like the java code of UDF you are creating is referring PIG libraries. While creating Hive UDF you should include hive library. I have mentioned whole Procedure in following link http://lets-do-something-big.blogspot.in/2014/02/hive-udf-example.html . Please let me know if you still face problem
pig 0.10.0 supports ruby UDF. So, i am trying a very simple example. but got the following error. Do you know why?

I had the same problem. You should look to see if you have a jruby.jar installed w pig.
Seems like the jython.jar was there so maybe that's a friendly nudge for people to use python.
I had to explicitly put the jruby.jar in the classpath doing:
java -cp $PIG_HOME/pig-0.11.1.jar:$PIG_HOME/lib/jruby.jar org.apache.pig.Main -x local myscript.pig
I have Hadoop and Zookeeper running w/o a problem but when I go to run $ACCUMULO_HOME/bin/accumulo init, this happens:

I can't see to find anything helpful.
This error occurs when trying to run from the source code without compiling it with Maven.
I assume this may have been resolved by now?
If not, looks like Accumulo has not been compiled correctly.
If your using the Binary Dist, run the following to compile.
mvn package -P assemble
I am using the org.apache.mahout.cf.taste.hadoop.pseudo.RecommenderJob.java file to run a pseudo distributed recommender. I am using it to run the GenericItemsRecommender class.
The command I am using is
bin/hadoop jar mahout-core-0.7-SNAPSHOT-job org.apache.mahout.cf.taste.hadoop.pesudo.RecommenderJob -Dmapred.input.dir=./ratingsLess.txt -Dmapred.output.dir=/input/output --tempDir /input/tmp --recommenderClassName org.apache.mahout.cf.taste.impl.recommender.GenericItemBasedRecommender
When I run it I get an Exception saying :
