Rakesh Radhakrishnan updated HDDS-6040:
---------------------------------------
Description:
This task is to discuss and implement upgrade finalization. Also, should
support downgrades from pre-finalized state of OM.
Overall Upgrade logic could be like,
OM should not allow to create FSO/OBS layouts before finalization. If client
pass FSO/OBS layouts explicitly then should throw exception. Also, won't
persist layout into RocksDB before finalization.
*Task-1)* HDDS-6200
*Task-2)* ClientBucketLayoutValidator - Before finalization, if client sends
explicit bucket layouts (FSO and OBS) in OM server and throw exception. **
