I don't know if we "want to", but it is the current behaviour. A job should
only fail if its restart strategy is exhausted though. Do you think we should
change that behaviour?

> Submitting a job in Yarn with HA can lead to the following exception:

> Some job information, including the Blob ids, are stored in Zookeeper. The
> actual Blobs are stored in a dedicated BlobStore, if the recovery mode is set
> to Zookeeper. This BlobStore is typically located in a FS like HDFS. When the
> cluster is shut down, the path for the BlobStore is deleted. When the cluster
> is then restarted, recovering jobs cannot restore because it's Blob ids
> stored in Zookeeper now point to deleted files.
