> Currently, the translator removes bucketing info for tables for clients that do not possess the HIVEBUCKET2 capability. While this is desirable, some clients that have write access to these tables can turn around overwrite the metadata thus corrupting original bucketing info.
> So adding support for a capability for client that are capable of interpreting the original metadata would prevent such corruption.
