Hi Mitchell,
worker.yaml and worker.pid are used by storm itself.
They will be put into {STORM_WORKERS_ARTIFACTS_DIR}/{worker id}/{worker port}
(see
https://github.com/apache/storm/blob/master/storm-client/src/jvm/org/apache/storm/utils/ConfigUtils.java#L259-L261
<https://github.com/apache/storm/blob/master/storm-client/src/jvm/org/apache/storm/utils/ConfigUtils.java#L259-L261>
https://github.com/apache/storm/blob/master/storm-client/src/jvm/org/apache/storm/utils/ConfigUtils.java#L104-L114
<https://github.com/apache/storm/blob/master/storm-client/src/jvm/org/apache/storm/utils/ConfigUtils.java#L104-L114>)
If you want to change their location, you can set this config:
“STORM_WORKERS_ARTIFACTS_DIR” (
https://github.com/apache/storm/blob/master/storm-client/src/jvm/org/apache/storm/Config.java#L1751-L1757
<https://github.com/apache/storm/blob/master/storm-client/src/jvm/org/apache/storm/Config.java#L1751-L1757>)
