> Currently, hive supports "rollback" feature. Once rolledback,  it is not possible to move from older snapshot to newer snapshot.
> It ends up throwing {color:#0747a6}"org.apache.iceberg.exceptions.ValidationException: Cannot roll back to snapshot, not an ancestor of the current state:" {color}error.
> It will be good to support "set_current_snapshot" function to move to different snapshot ids.
