> The hcat prepare only allows to drop partitions. It would be nice to also 
> allow dropping of table, depending on the URL. The current format of the URL 
> is
> {code}hcat://[metastore server]:[port]/[database name]/[table 
> name]/[partkey1]=[value];[partkey2]=[value]{code}
> where at least one partition must be provided, otherwise the prepare step 
> fails with the fololwing exception.
