d804701 is described below
commit d804701966d719b132f0bd4a48496dc12aef459e
Author: Rajan Dhabalia <rdhaba...@apache.org>
AuthorDate: Mon Aug 20 23:20:40 2018 -0700
Add admin api to support stop function (#2415)
### Motivation
We have a usecase where we want to stop the function temporary to avoid
draining on that function topics. So, adding an admin api/cli to stop function.
### Modifications
- add REST/CLI api to stop function.
### Result
we can stop and then restart function with admin/cli api.
