 * Indicates a specific task is corrupted and need to be re-initialized. It can be thrown when:
 *
 * 
 *   Under EOS, if the checkpoint file does not contain offsets for corresponding store's changelogs, meaning previously it was not close cleanly.
 *   Out-of-range exception thrown during restoration, meaning that the changelog has been modified and we re-bootstrap the store.
