今天跑了一个mr，报错了 Container [pid=23093,containerID=container_1619340363070_0046_01_000008] is running beyond virtual memory limits. Current usage: 196.9 MB of 1 GB physical memory used; 2.1 GB of 2.1 GB virtual memory used. Killing container. 感觉应该是虚拟内存，不够用了。 hadoop-2.6.5/etc/hadoop/ yarn-site.xml 参考网址： https://hadoop.apache.org/docs/r2.6.5/hadoop-yarn/hadoop-yarn-common/...
