Openstack Sahara CDH Cluster hat Warnmeldungen

Question

Ich habe einen Cloudera Hadoop Cluster mit Sahara CDH Plugin 5.4.0 mit 1 Master-Knoten und 2 Arbeiter Knoten erstellt. Cloudera Manager meldet die folgenden Warnmeldungen:

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 

Dann schaute ich in Master-und Worker-Knotengruppenvorlagen. Ich kann dfs.datanode.data.dir, dfs.namenode.name.dir, yarn.nodemanager.local-dirs oder dfs.namenode.checkpoint.dir Parameter nicht finden, wo ich Datenverzeichnispfad geben kann.

Bitte lassen Sie mich wissen, wenn ich etwas in der Vorlagenkonfiguration vermisse. Ich schätze jede Hilfe.

Dank
