how to switch another use other than vagrant to execute ansible modules?

[bronzels]

hi, this guest_plugin plugin helps me to use windows as host to use ansible. my user account in centos guest is always hadoop as i am working on hadoop. for shell module to execute a script or command, it is OK to su. it is OK to use shell module like "echo "hadoop password"|su hadoop xxxx". but when i try to use other modules, i can't switch to hadoop user by user or remote_user settings in yml. all modules execution failed. anyway to switch from vagrant user to another user?
