>                 Key: SPARK-21083
>                 URL: https://issues.apache.org/jira/browse/SPARK-21083
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL
>    Affects Versions: 2.3.0

> 1. When we first analyze without `noscan` and then analyze with `noscan`, the table is not changed, so we should keep row count in statistics.
> 2. When we first analyze one column in table and then analyze another column, the table is not changed, so we should keep the previous column stats and combine them with the newly collected column stats.
