> {{msck repair table <tablename>}} is often used in environments where the new
> partitions are loaded as directories on HDFS or S3 and users want to create
> the missing partitions in bulk. However, currently it only supports addition
> of missing partitions. If there are any partitions which are present in
> metastore but not on the FileSystem, it should also delete them so that it
> truly repairs the table metadata.
> We should be careful not to break backwards compatibility so we should either
> introduce a new config or keyword to add support to delete unnecessary
> partitions from the metastore. This way users who want the old behavior can
> easily turn it off.
