------------------------------
Summary: 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
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.
