@avijayanhwx @bharatviswa504 Thank you for telling me HDDS-3668 can help me to resolve my problem. - Yeah, indeed, i believe HDDS-3668 is a better way, but when i met the problem caused by HDDS-3614, there aren't HDDS-3668 yet, so have to build and install a ldb of rocksdb, and drop the S3Table column family to resolve the problem, in fact, we haven't patch HDDS-3668 still now, and OM can successfully work by remove the useless table by the ldb of rocksdb. - HDDS-3668 is a way to avoid start failed with the unexpected column family, but we still want to remove the useless column family from rocksdb like the `S3Table`, when i think we don't need this table, i need a way to remove the column family. - Adding capability to create/delete tables using a debug tool is risky I agree, but we need it. In fact, without this PR, i can still create/delete the rocksdb by rocksdb/ldb, even i can remove the rocksdb persistent file on the disk, because i'm the administrator of this Ozone cluster, so i think we should prevent anybody/user to do the risky operation to Ozone cluster, but we should let someone with high permission of the cluster like me can do something they know they can do safety, and they can be responsible for the risk by their operation. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
