我有一个在hive 13（YARN）上运行良好的脚本我正在试验tez。当我在大型数据集上运行查询时，我会遇到以下错误。

EMR集群的一些规格-m1.x大型主节点、4个r3.8大型核心节点、2个r3.8小型任务节点（约1.3 TB内存）
我尝试了以下设置，但它们不起作用。
set tez.task.resource.memory.mb=8000;
SET hive.tez.container.size=30208;
SET hive.tez.java.opts=-Xmx24168m;
此外，由于亚马逊在EMR上提供了0.4.1版本的tez，我现在正在运行它（也许这就是问题所在？）
有人能帮我修复它吗？我试图围绕一些与内存相关的属性进行调整，比如mapreduce.map.memory.mb，但还没有成功。
尝试更改tez.task.resource.memory.mb
这是在Tez上下文中用于映射内存和减少内存的参数。
检查您的yarn site.xml，并使用以下属性：
