Boyang Jerry Peng commented on STORM-1631:
------------------------------------------
One bug is in function kill-existing-workers-with-change-in-components in
supervisor.clj:
The function tries to detect whether there is a change in assignment. The bug
in this function is that the ordering of the assignment matters but it
shouldn't. For example, if a worker assignment is [[1 1] [2 2]] and it changed
to [[2 2] [1 1]] it will cause the supervisor to restart the worker
> Storm CGroup bug when launching workers as the user that submitted the
> topology

> In secure multitenant storm, topology workers are launched with permission of
> the user that submitted the topology. This causes a problem with cgroups
> since workers are launched with permissions of the topology user which does
