> suppose the following scenario:
> * part1 has basic stats {{RC=10,DS=1K}}
> * all other partition has no basic stats (and a bunch of rows)
> then [this|https://github.com/apache/hive/blob/d9924ab3e285536f7e2cc15ecbea36a78c59c66d/ql/src/java/org/apache/hadoop/hive/ql/stats/StatsUtils.java#L378]
condition would be false; which in turn produces estimations for the whole partitioned table:
{{RC=10,DS=1K}}
