Hyukjin Kwon resolved SPARK-17603.
----------------------------------
Resolution: Incomplete
> Utilize Hive-generated Statistics For Partitioned Tables
> --------------------------------------------------------
>
> Key: SPARK-17603
> URL: https://issues.apache.org/jira/browse/SPARK-17603
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0, 2.1.0
> Reporter: Xiao Li
> Priority: Major
> Labels: bulk-closed
>
> For non-partitioned tables, Hive-generated statistics are stored in table
> properties. However, for partitioned tables, Hive-generated statistics are
> stored in partition properties. Thus, we are unable to utilize the
> Hive-generated statistics for partitioned tables.
> The statistics might not be gathered for all the partitions in Hive. For
> partial collection, we will not utilize the Hive-generated statistics.
