# Throughout this file, pylint has trouble understanding that EnvFactory

# and subscriptable objects. Various warnings are disabled because of this.
# See also a comment about self._rsh in environment.py.
# pylint: disable=unsubscriptable-object
# pylint doesn't understand that self._rsh is callable (it stores the
# singleton instance of RemoteExec, as returned by the getInstance method
# of RemoteFactory). It's possible we could fix this with type annotations,
# but those were introduced with python 3.5 and we only support python 3.4.
# I think we could also fix this by getting rid of the getInstance methods,
# but that's a project for another day. For now, just disable the warning.
# pylint: disable=not-callable
# ClusterManager has a lot of methods.

class ClusterManager(UserDict):
'''The Cluster Manager class.
This is an subclass of the Python dictionary class.
(this is because it contains lots of {name,value} pairs,
not because it's behavior is that terribly similar to a
dictionary in other ways.)
This is an abstract class which class implements high-level
operations on the cluster and/or its cluster managers.
Actual cluster managers classes are subclassed from this type.
One of the things we do is track the state we think every node should
be in.
