[SPARK-8794][SQL] Make PrunedScan work for Sample
JIRA: https://issues.apache.org/jira/browse/SPARK-8794
Currently `PrunedScan` works only when followed by project or filter
operations. However, even if there is a `Sample` between these operations and
`PrunedScan`, `PrunedScan` should work too.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/viirya/spark-1 sample_prunedscan
