+## 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
+    ```
