-----------------------------------
Summary: Prevent deletion of topology blobs during initial
scheduling
Key: STORM-3586
URL: https://issues.apache.org/jira/browse/STORM-3586
Project: Apache Storm
Issue Type: Bug
Reporter: Aaron Gresch
Assignee: Aaron Gresch
If a cluster has a long scheduling period compared to the blob cleanup
interval, it's possible to have a user submit a topology, kill it, and have the
blob removed before supervisors get the scheduling assignment. If this
happens, the supervisors will get FNF exceptions looking for the blob.
A simple fix is to just have the blob cleanup interval be larger than the
scheduling timeout.
