regarding configuring jython with intellij idea python plugin

I switched to IntelliJ IDEA at workplace (team reasons)

And evaluated the intellij python plugin with jython 2.7.0 on my MAC OS X
10.9.5

I download the jython installer and went through the installation procedure
before using the python plugin of IntelliJ IDEA

In IntelliJ IDEA we have to setup a python SDK which can be used for
executing python scripts which I did promptly by pointing towards the
jython executable file.
While trying to run a python script (of reasonable complexity with lots of
java and python modules dependencies ) , *I got the following error* :

Exception in thread “main” ImportError: Cannot import site module and its
dependencies: No module named site
Determine if the following attributes are correct:

   - sys.path: [‘/opt/jython2.7.0/Lib1’, ‘/opt/python-dateutil-1.5’,
   ‘/Users/someuser/.m2/repository/org/apache/hive/shims/hive-shims-common/0.13.0/hive-shims-common-0.13.0.jar’,
   * elided a lot of jars * , ‘/opt/jython2.7.0/Lib’, ‘*classpath*‘, ‘
   *pyclasspath*/‘]
   This attribute might be including the wrong directories, such as from
   CPython
   - sys.prefix: /opt/jython2.7.0
   This attribute is set by the system property python.home, although it can
   be often automatically determined by the location of the Jython jar file

You can use the -S option or python.import.site=false to not import the
site module
On using -S switch, I got more frustrating errors

Traceback (most recent call last):
File
“/Users/debabratapani/mobileum/work/code/datamodel/oozie/DomesticAverage/ProcessDomesticAverageAction.py”,
line 6, in
import oozie.common.dataset as dataset
File
“/Users/debabratapani/mobileum/work/code/datamodel/oozie/common/dataset.py”,
line 4, in
import re
*ImportError: No module named re*

*How is -S causing this ? *
Removed the -S switch and add the following environment variable

JYTHONPATH=/opt/jython270/Lib

*It went through fine*
I don’t need to add this environment variable when i use the jython
executable itself.

*Suggestion why this is required?*

After this configuration headache, using IntelliJ IDEA with python plugin
is breeze.
