Hi,
I am trying to run a python script '/sbin/gluster-eventsapi' in vdsm verb which internally imports some python modules from /usr/lib/python2.7/site-packages/gluster/cliutils/. But it fails with the import error. Following error is seen in the supervdsm log.
MainProcess|Thread-1::DEBUG::2016-11-28 16:54:35,130::commands::93::root::(execCmd) FAILED: <err> = 'Traceback (most recent call last):\n File "/sbin/gluster-eventsapi", line 25, in <module>\n from gluster.cliutils.cliutils import (Cmd, execute, node_output_ok, node_output_notok,\nImportError: No module named cliutils.cliutils\n'; <rc> = 1
I think the import statement "from gluster.cliutils.cliutils import (Cmd, execute, node_output_ok, node_output_notok)" in the python script resolves to '/usr/share/vdsm/gluster' instead of /usr/lib/python2.7/site-packages/gluster/cliutils.
I see the following in python sys.path while executing a python script from vdsm.
['/usr/libexec/glusterfs', '/usr/share/vdsm', '/usr/lib64/python27.zip', '/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', '/usr/lib64/python2.7/site-packages', '/usr/lib64/python2.7/site-packages/gtk-2.0', '/usr/lib/python2.7/site-packages']
Looks like '/usr/share/vdsm' take precedence over '/usr/lib64/python2.7/site-packages'.
Can someone suggests a way to fix this issue?
Note: '/sbin/gluster-eventsapi' works perfectly while running directly from CLI.

If an import fails because /usr/share/vdsm/foo hides a package in /usr/lib/python2.7/site-packages/vdsm it means that you have a wrong import, you need to import anything like this: from vdsm.foo import bar So names in /usr/share/vdsm/* cannot hide names in vdsm package. Nir
