Zhenhua Wang updated SPARK-21083:
---------------------------------
Description: (was: 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.)
> Store zero size and row count after analyzing empty table
