Description
The
ResultFileDownloadManagerin theCloudFetchQueueis not shut down alongside theResultSet.The
ResultFileDownloadManageron being requested for a file ensures that the "download queue is always full", i.e. it adds uptomax_download_threadsFutures into_download_tasks. In caseResultSet.close()is invoked after this,_shutdown_manager(defined forResultFileDownloadManager) is NOT called, so these Futures keep executing in the background and the files keep being downloaded.We define a
closefor theCloudFetchQueuethat invokes_shutdown_manager.How is this tested?
