-------------------------------------
Summary: current update stats for columns of a partition of a
table is not correct
Key: HIVE-7944
URL: https://issues.apache.org/jira/browse/HIVE-7944
Project: Hive
Issue Type: Bug
Reporter: pengcheng xiong
Assignee: pengcheng xiong
We worked hard towards faster update stats for columns of a partition of a
table previously
https://issues.apache.org/jira/browse/HIVE-7736
and
https://issues.apache.org/jira/browse/HIVE-7876
Although there is some improvement, it is only correct in the first run. There
will be duplicate column stats later. Thanks to [~ekoifman] 's comments
