according directions of openstack official heat/plugins wiki https://wiki.openstack.org/wiki/heat/plugins, need "to install plugin, copy python modules 1 of configured plugin directories. note heat-engine must restarted after in order load new plugins.". hit following error messages after restart heat-engine..

/usr/lib/heat /usr/lib/heat/abc_heat_plugin /usr/lib/heat/abc_heat_plugin/client 2) copy plugin "my_heat_plugin" /usr/lib/heat
3) restart heat service
but both ways have more official guide, wonder whether missed important. suggestions? thanks. (btw, my_heat_plugin working well.)
i think basic idea drop resource in /usr/lib/heat, modules or packages used resource must installed usual way. sort of did manually moving files site-packages.
take @ of plugins in heat/contrib example. there few have dependencies such clients other openstack services, , in cases assumption made clients installed separately.
so if can, create setup.py client package, , install separately heat plugin.
