Prepare to replicate Iceberg tables stored in Ozone buckets

Complete the mandatory requirements before replicating the Iceberg tables stored in Ozone.

File system optimized (FSO) and object store (OBS) are bucket layouts in Ozone. FSO buckets are Hadoop-compatible file system buckets. OBS buckets can be accessed using the S3 interface provided by Ozone where all the keys are written into a flat namespace.

When you use the Ozone shell to create an Ozone bucket, it intuitively uses the right interface or gateway to create the bucket. For example, when you create an FSO bucket, the shell uses the Ozone file system (OFS) client that is an compatible interface to create the bucket. Similarly, when you create an OBS bucket, the shell uses the AWS S3-compatible gateway.
