答案 0 :(得分：0)

根据提供的日志，您正在Tez上运行map join，但在加载hashMap时失败。 java.lang.OutOfMemoryError: GC overhead limit exceeded是一个例外。

尝试增加映射器容器的大小和Java堆的大小。检查您当前的配置并相应增加。这仅是示例：

set hive.tez.container.size=9216;
set hive.tez.java.opts=-Xmx6144m;

可以在以下位置找到关于这些配置参数的良好调整指南：Demystify Apache Tez Memory Tuning - Step by Step
如果没有任何帮助，可能是表太大而无法容纳在内存中，请考虑减小hive.auto.convert.join.noconditionaltask.size的值，以强制查询对这种大表使用随机组合。
