Hi @revans2 and @tgravescs ,
For checking all cases of relative/absolute directory for healthcheck, I
would suggest to add the following function in config.clj, then healthcheck.clj
can all this function to get the directory.
(defn absolute-healthcheck-dir [conf]
(let [storm-home (System/getProperty "storm.home")
path (conf STORM-HEALTH-CHECK-DIR)]
(if path
(if (is-absolute-path? path) path (str storm-home file-path-separator
path))
(str storm-home file-path-separator “healthcheck”))))
> 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.
