             Summary: Backport HIVE-24965: Describe table partition stats fetch should be configurable
                 Key: HIVE-24984
                 URL: https://issues.apache.org/jira/browse/HIVE-24984
             Project: Hive
          Issue Type: Improvement
    Affects Versions: 3.1.2, 3.1.1, 3.0.0
            Reporter: Kevin Cheung
            Assignee: Kevin Cheung
             Fix For: 3.1.3


In certain 3rd party hive UIs, they issue a describe table command, and usually it's either "describe formatted table" or "describe extended table", and it will take a very long time for highly partitioned tables (10k+). In the UI, there is no way to change the settings (to use "describe table"), thus impairing the user experience. Prior to the feature where partition stats was gathered, the experience with using the UI had no problems.

This will allow users to selectively change the describe formatted/extended table behavior at any time.

 

*The setting will be:*
 hive.describe.partitionedtable.ignore.stats = false; – default behavior (no user impact)

 

Backport https://issues.apache.org/jira/browse/HIVE-24965 into branch-3.1
