> Fix race condition is async localizer
> -------------------------------------
>
> Key: STORM-3020
> URL: https://issues.apache.org/jira/browse/STORM-3020
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-server
> Affects Versions: 2.0.0
> Reporter: Robert Joseph Evans
> Assignee: Robert Joseph Evans
> Priority: Major
> Labels: pull-request-available
>
> I think this impacts all of the code that uses asynclocalizer, but I need to
> check to be sure.
> As part of a review of a different pull request against AsyncLocalizer I
> noticed that requestDownloadTopologyBlobs is synchronized, but everything it
> does is async, but there is a race in one of the async pieces where we read
> from a map, and then try to update the map later, all outside of a lock.
