Please set the PYTHONPATH variable before running the ambari python scripts.

Example:

# export PYTHONPATH=/usr/lib/python2.6/site-packages:/usr/lib/python2.6/site-packages/ambari_commons:/usr/lib/python2.6/site-packages:/usr/lib/python2.6/site-packages:/usr/lib/python2.6/site-packages/ambari_commons:/usr/lib/python2.6/site-packages::/usr/lib/python2.6/site-packages:/usr/lib/python2.6/site-packages/ambari_agent:/usr/lib/python2.6/site-packages

As the original query which was asked in the HCC thread is addressed hence i will suggest you to close this thread by clicking on the "Accept" Button on the correct answer.

Then open a separate HCC thread for your latest query that way it helps in maintaining one thread dedicated to one particular issue/query and helps HCC users to find the correct answers quickly instead of going through side issues.

ok! Thank you!
