HIVE 0.11版本的bug

两次{{group by}}的bug \ https://issues.apache.Z喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcmcvamlyYS9icm93c2UvSElWRS01MTQ5PGJyPgo8cHJlIGNsYXNzPQ=="brush:sql;">SELECT key, COUNT(*) FROM ( SELECT key, value, COUNT( * ) FROM src GROUP BY key, value ) a GROUP BY key;
特点是两次 group by ,外层字段少于内层,2次集合函数。可以把中间的查询做成临时表回避这个bug
HIVE 0.12修复了这个bug

对于分区表中, alter table foo add columns bar string 添加列后,已有分区的新增的列永远是NULL,即使 drop 分区重建也不行。 必须删表重新指定分区。https://issues.apache.org/jira/browse/HIVE-2615
