----------------------------------------
Summary: Persist row and column stats for HDFS directory across multiple
external tables (was: Persist table and column stats for HDFS directory across
multiple external tables)

> 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
