How cloudera manage role stop start in

How cloudera manage role stop start in


I found Cloudera uses which is installed under /usr/lib64/cmf/agent/src/cmf/ In this python script, it has a Proess class to stop start roles such as datanode, nodemanger etc. This is in CM 5.5


But I found the is no longer under /usr/lib64/cmf/agent/src/cmf/ but under /usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/cmf-5.9.0-py2.6.egg/lib/cmf/ and



And  cannot found the Process class in those anymore.


So how does in CM 5.9 manage the roles? We need to moify the code to do some checks before starting a role.
