[SPARK-11448][SQL] Skip caching part-files in driver side when configured
to merge schema and respect summaries
JIRA: https://issues.apache.org/jira/browse/SPARK-11448
We now cache part-files, metadata, common metadata in ParquetRelation as
currentLeafStatuses. However, when configured to merge schema and respect
summaries, dataStatuses (`FileStatus` objects of all part-files) are not
necessary anymore. We should skip them when caching in driver side.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/viirya/spark-1 skip-part-files-as-leaves
Alternatively you can review and apply these changes as the patch at:
