> A bug in the namenode web UI can lead to unexpected deletion of files. When a
> file is selection for deletion but the cancel button is pressed in the modal
> popup the modal is hidden but the event is not deleted. A subsequent delete
> operation will delete all files previously selected for deletion but
> cancelled as well as the the intended file.
> The following steps can be used to reproduce this issue:
> * Open the namenode web UI and select utilities -> Browse the file system
> * Click on the trashcan delete icon next to a file
> * Click the cancel button on the delete confirmation modal
> * Click in the delete icon for a different file
> * Click the Delete button on the delete confirmation modal
> * Both files are deleted
