             Summary: Fix off-by-factor-of-8 error when allocating scratch space in UnsafeFixedWidthAggregationMap
                 Key: SPARK-8354
                 URL: https://issues.apache.org/jira/browse/SPARK-8354
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Josh Rosen
            Assignee: Josh Rosen


UnsafeFixedWidthAggregationMap contains an off-by-factor-of-8 error when allocating row conversion scratch space: we take a size requirement, measured in bytes, then allocate a long array of that size.  This means that we end up allocating 8x too much conversion space.
