> HMS stores table and column stats for table which are tightly coupled to table names/ids.
> Instead, these computed stats should be tied to HDFS directory, so that even any external
table created should be able to reuse and take advantage of previously computed stats. This
conserves compute resources as there will be no need to expend them doing same work on same
HDFS directory just for a different table name string
