DROP TABLE deletes the table and removes the directory associated with the table from the file system if the table is not EXTERNAL table. If the table is not present it throws an exception.

In case of an external table, only the associated metadata information is removed from the metastore database.

If the table is cached, the command uncaches the table and all its dependents.
