pyspark报错，An error occurred while calling o123.saveAsTable

刚开始去网上搜
An error occurred while calling o123.saveAsTable 被误导了，

真实原因：
内存不够，OOM了。

真实报错：
Container killed by YARN for exceeding physical memory limits. 123 GB of 12 GB physical memory used.

解决方案：
把repartition调大：
data_frame.rdd.repartition(100000)
