[jira] [Created] (HIVE-10900) Fix the indeterministic stats for some hive queries

Pengcheng Xiong created HIVE-10900:
--------------------------------------

             Summary: Fix the indeterministic stats for some hive queries 
                 Key: HIVE-10900
                 URL: https://issues.apache.org/jira/browse/HIVE-10900
             Project: Hive
          Issue Type: Improvement
            Reporter: Pengcheng Xiong
            Assignee: Pengcheng Xiong
            Priority: Minor


If we do not run compute stats for a table and then we do some operation on that table, we will get different stats numbers when we run explain. The main reason is due to the different OS/FS configurations that Hive Stats depends on when there is no table stats. A simple fix is to add compute stats for those  indeterministic stats.
