> Key: HDDS-6259

> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
>
> With a small key less than 1 chunk, if the replica with index 1 is up, but
> more than parity_num other replicas are not available, attempting to read the
> key gives an insufficient datanode errors. Ideally, as index_1 is present,
> and the keyLength is less than 1 chunk, the data should be readable.
> A similar scenario for a key less than 1 chunk, is that indexes 1, 2, 3 and 4
> OR 5 are down. As we know 2 and 3 are only zeros, and we have a single
> parity, we should be able to reconstruct this, but again it fails with an
> insufficient datanodes error.
