------------------------------------------
Summary: Simplify Threading Model of the Supervisor
Key: STORM-2018
URL: https://issues.apache.org/jira/browse/STORM-2018
Project: Apache Storm
Issue Type: New Feature
Components: storm-core
Affects Versions: 1.0.0, 2.0.0
Reporter: Robert Joseph Evans
Assignee: Robert Joseph Evans
We have been trying to roll out CGROUP enforcement and right now are running
into a number of race conditions in the supervisor. When using CGROUPS the
timing of some operations are different and are exposing issues that we would
not see without this.
In order to make progress with testing/deploying CGROUP and RAS we are going to
try and refactor the supervisor to have a simpler threading model, but likely
with more threads. We will base the code off of the java code currently in
master, and may replace that in the 2.0 release, but plan on having it be a
part of 1.x too, if it truly is more stable.
I will try to keep this JIRA up to date with what we are doing and the
architecture to keep the community informed. We need to move quickly to meet
some of our company goals but will not just shove this in. We welcome any
feedback on the design and code before it goes into the community.
