-----------------------------------------
Summary: Automatic Black Listing of bad nodes
Key: STORM-909
URL: https://issues.apache.org/jira/browse/STORM-909
Project: Apache Storm
Issue Type: Improvement
Reporter: Robert Joseph Evans
We should be able to detect and monitor the failure rate of workers on nodes,
and come up with a few different probabilities. How likely is it that this
worker will fail on this particular node in the next n mins. How likely is it
that all workers will fail on this particular node in the next n mins. How
likely is it that this worker will fail on any node in the next n mins.
With these we should be able to detect bad nodes and blacklist them, and
ideally trigger external systems that can take actions to try and fix the
nodes. We should also be able to detect topologies that have bugs in the
common case warn them, and in the worst case stop trying to run them.
