[jira] [Created] (SPARK-9450) HashedRelation.get() could return an Iterator[Row] instead of Seq[Row]

Josh Rosen created SPARK-9450:

             Summary: HashedRelation.get() could return an Iterator[Row] instead of Seq[Row]
                 Key: SPARK-9450
                 URL: https://issues.apache.org/jira/browse/SPARK-9450
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Josh Rosen


While looking through some HashedRelation code, [~andrewor14] and I noticed that it looks like HashedRelation.get() could return an Iterator of rows instead of a sequence.  If we do this, we can reduce object allocation in UnsafeHashedRelation.get().
