Tanvi Penumudy commented on HDDS-11348:
---------------------------------------
The patch causing the regression skips the getBucket() check when we already
know that the bucket exists, but this also results in skipping of the
validation check on the client-side. The only way we can restrict the operation
from the client-side is to make the getBucket() call (an additional round trip
to OM to obtain this layout information - that the patch skips).
Therefore, I think the only way to go about this is to revert this patch.
On the server-side, we do not throw any exception as such (if we did, we might
have been able to handle it on the client-side for OBS buckets accordingly).
So, I do not think it's possible to address this situation without having to
change the server-side behaviour, especially if we want to avoid the additional
getBucket() call on the client side.

> 'fs -mkdir' is creating directories for OBS type bucket
> Other fs operations such as _ls_ and _copyfromLocal_ are throwing unsupported

> -copyFromLocal: Bucket: buck1 has layout: OBJECT_STORE, which does not
> support file system semantics. Bucket Layout must be FILE_SYSTEM_OPTIMIZED or
> LEGACY. {code}

> -ls: Bucket: buck1 has layout: OBJECT_STORE, which does not support file
> system semantics. Bucket Layout must be FILE_SYSTEM_OPTIMIZED or LEGACY.
> {code}
> Its working correctly with _mkdir_ operation -
