> Currently, the partition metadata is inferred from the table being inserted into.
> So, it is not possible to convert a old partition to RCfile unless the table is first converted to RCFile, and the older
> partition then inserted into.
> But, for some reason, if the table cannot be converted to RCFile (say a old process is loading data into that table),
> there is no way to convert the older partition from sequence file to rcfile.
> There should be a way to do so, something like:
> insert overwrite table T partition (..) 
> select......
> stored as RCFile;
