这是我正在使用的以下查询,每次我得到以下语义分析错误。
hive> select explode(test2.purchased_item.product_id) AS prodID,
explode(test2.purchased_item.timestamps) AS time from testingtable2 test2;
FAILED: Error in semantic analysis: Only a single expression in the SELECT clause
is supported with UDTF's
我不能在单个选择语句中使用两个爆炸的蜂巢有什么限制吗?
