## 问题
### nodemanager 没有优雅退出
- 异常描述：执行脚本 $HADOOP_HOME/sbin/stop-yarn.sh 停止 yarn 时，终端报“nodemanager did not stop gracefully after 5 seconds: killing with kill -9”
- 解决办法：修改脚本 $HADOOP_HOME/sbin/stop-yarn.sh，修改脚本最后的停止顺序，即先停止 nodemanager，最后停止 resourcemanager
```bash
# stop nodeManager
"$bin"/yarn-daemons.sh --config $YARN_CONF_DIR stop nodemanager
# stop proxy server
"$bin"/yarn-daemon.sh --config $YARN_CONF_DIR stop proxyserver
# stop resourceManager
"$bin"/yarn-daemon.sh --config $YARN_CONF_DIR stop resourcemanager
```
