Openstack撒哈拉CDH群集有警告提示

Question

我已经使用Sahara CDH插件5.4.0创建了一个Cloudera Hadoop群集，其中包含1个主节点和2个工作节点。 Cloudera Manger报告了以下警告警报：

hdfs01: DataNode Data Directory 
Missing required value: DataNode Data Directory 
hdfs01: HDFS Checkpoint Directories 
Missing required value: HDFS Checkpoint Directories 
hdfs01: NameNode Data Directories 
Missing required value: NameNode Data Directories 
yarn01: NodeManager Local Directories 
Missing required value: NodeManager Local Directories 

然后我查看了主节点组和工作节点组模板。我找不到dfs.datanode.data.dir,dfs.namenode.name.dir,yarn.nodemanager.local-dirs或dfs.namenode.checkpoint.dir参数，我可以给出数据目录路径。

如果我在模板配置中丢失了某些东西，请让我知道。我感谢任何帮助。

感谢
