agresch opened a new pull request #3144: STORM-3524 create complete blobstore path in case parent directory ge… URL: https://github.com/apache/storm/pull/3144 …ts deleted Based on the exception I saw on a supervisor, I think a race condition existed between a cleanup of the localizer for an older topology and a new one starting where a parent directory was deleted right before a download. Files.createDirectory() then throws an exception because the parent directory does not exist and can never succeed. Files.createDirectories() should guarantee the directory gets created. Also added logging for removing the user to better debug in the future.
