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

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...
I am getting the following error when tried to execute hive command line interface. May I know the incompatible Jar files causing the problem and the solution to fix it?

Is it that i have to include jar or what else can be the issue
Thanks
You need to include the mapred java archive, depending on which MapReduce version you use, MRv1 or MRv2 (=YARN).
FYI: java.lang.NoClassDefFoundError is always about a forgotten/mistyped JAR-file
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
