Jython import error

I'm trying to build a unit test using jython, but when I run the example I get the error due to my import of the Sha1Hash. The error and the classes are below. I don't understand why. What's the error?

Running execution:

Code:

import org.apache.hadoop.mapreduce.security as Sha1Hash
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named apache

Python class

Code:

#!/usr/bin/env jython

import org.apache.hadoop.mapreduce.security as Sha1Hash

import unittest

class TestSha1Hash(unittest.TestCase):
    def test_sha1(self):
		sentence="The quick brown fox jumps over the lazy dog"
		print sentence

		#Sha1Hash sha = new Sha1Hash()


if __name__ == '__main__':
	unittest.main()
