------------------------------------
Summary: Supervisor recurring health checks
Key: STORM-1155
URL: https://issues.apache.org/jira/browse/STORM-1155
Project: Apache Storm
Issue Type: Improvement
Components: storm-core
Reporter: Thomas Graves
Assignee: Thomas Graves
Add the ability for the supervisor to call out to health check scripts to allow
some validation of the health of the node the supervisor is running on.
It could regularly run scripts in a directory provided by the cluster admin. If
any scripts fail, it should kill the workers and stop itself.
This could work very much like the Hadoop scripts and if ERROR is returned on
stdout it means the node has some issue and we should shut down.
If a non-zero exit code is returned it indicates that the scripts failed to
execute properly so you don't want to mark the node as unhealthy.
