Apache Spark reassigned SPARK-17868:
------------------------------------
Assignee: Apache Spark
> Do not use bitmasks during parsing and analysis of CUBE/ROLLUP/GROUPING SETS
> ----------------------------------------------------------------------------
>
> Key: SPARK-17868
> URL: https://issues.apache.org/jira/browse/SPARK-17868
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Herman van Hovell
> Assignee: Apache Spark
>
> We generate bitmasks for grouping sets during the parsing process, and use
> these during analysis. These bitmasks are difficult to work with in practice
> and have lead to numerous bugs. I suggest that we remove these and use actual
> sets instead, however we would need to generate these offsets for the
> grouping_id.
