> The Mpack Instance manage is producing JSON output which cannot be parsed by non-Python parsers:
> - Includes unicode markers for strings (like \{{u'ZOOKEEPER'}})
> - Uses non-standard single quotes
> {code}
> [root@c7403 mpack-instance-manager]$ python mpack-instance-manager.py list-instances
> {'mpacks': \{'hdpcore': {'mpack-instances': {'HDPCORE': {'name': 'HDPCORE', 'subgroups': {'default': {'modules': {'zookeeper': {'category': u'SERVER', 'name': 'zookeeper', 'components': {'zookeeper_server': {'component-instances': {'default': {'path': '/usr/hwx/mpacks/hdpcore/1.0.0-b450/zookeeper_server', 'name': 'default'}}}}}, 'zookeeper_clients': \{'category': u'CLIENT', 'name': 'zookeeper_clients', 'components': {'zookeeper_client': {'component-instances': {'default': {'path': '/usr/hwx/mpacks/hdpcore/1.0.0-b450/zookeeper_client', 'name': 'default'}}}}}}}}}}}}}
> {code}
> It also fails to provide information about the mpack version and component version. The output from the command \{{list-instances}} needs to provide both the mpack version and the module component version. Otherwise, this data cannot be reported back.
> If the \{{list-instances}} is not the correct command for this, then that's fine, but we still need a command we can invoke to get this information back in a structure manner.
