当我尝试运行配置单元查询以将数据插入到Hive外部表中时，我遇到了一个问题。该过程在减少时失败。
诊断控制台消息如下：

我为hive设置了动态分区：
set hive.exec.dynamic.partitions = true
set hive.exec.dynamic.partitions.mode = nonstrict
我还编写了namenode并再次尝试过，但错误不会发生。
答案 0 :(得分：-1)
问题的根本原因似乎与空间有关。我正在使用一个连接几个大表的查询，因为数据是偏斜的，Hive开始制作一个大的临时表，因为磁盘上没有空间。我将配置文件恢复为默认和压缩的中间结果（配置文件）以获得结果。
