------------------------------
Assignee: Gopal V
> Statistics: Provide per-column statistics expanded for "explain formatted"
> --------------------------------------------------------------------------
>
> Key: HIVE-20802
> URL: https://issues.apache.org/jira/browse/HIVE-20802
> Project: Hive
> Issue Type: Bug
> Reporter: Gopal V
> Assignee: Gopal V
> Priority: Major
>
> Debugging the internal per-column statistics of Hive is challenging,
> particularly when the estimations are approximate (hive.stats.estimate=true).
> Adding an extra columnStatistics field for all operators in "explain
> formatted" will allow tools to analyze the internal statistics transforms
> done by each operator without having to refer to debug logs.
