             Summary: Persist table and column stats for HDFS directory across multiple external tables
                 Key: HIVE-16807
                 URL: https://issues.apache.org/jira/browse/HIVE-16807
             Project: Hive
          Issue Type: New Feature
            Reporter: Mala Chikka Kempanna


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
