             Summary: HIVE_GROUPING_SETS_SIZE_LIMIT  too small
                 Key: HIVE-29153
                 URL: https://issues.apache.org/jira/browse/HIVE-29153
             Project: Hive
          Issue Type: Improvement
            Reporter: yongzhi.shao


{code:java}
if (!groupingSets.isEmpty() && groupByExprs.size() > Long.SIZE) {
  throw new SemanticException(ErrorMsg.HIVE_GROUPING_SETS_SIZE_LIMIT.getMsg());
} 
//  Long.SIZE = 64{code}
目前,我们发现,我们的用户开始使用100~200个groupByExprs,目前的最大限制64是否过于小了?
