Hi ALL,   I am trying to setup and configure cloudera hadoop cluster using API call in CM version 5.4.5. I have created and configure cluster and HDFS service using API calls. When I am trying to configure arguments to "hdfs-DATANODE-BASE"  roleConfgGroups, it gives 404 error. I can able to configure arguments for other roleConfigGroups(eg.hdfs-NAMENODE-BASE, hdfs-SECONDARYNAMENODE-BASE) using same api call. The hdfs-DATANODE-BASE" roleConfgGroups is available. Below is the curl api call to configure arguments to roleconfiggroups:   #curl -i -u admin:admin -X PUT  -H "content-type:application/json" -d '{"items":[{"name":"dfs_data_dir_list","value":"/data/dn1,/data/dn2,/data/dn3"},{"name":"dfs_datanode_failed_volumes_tolerated","value":"1"}]}'  http://localhost:7180/api/v10/clusters/TestCluster/services/hdfs/roleConfgGroups/hdfs-DATANODE-BASE/config     please help to fix it.   Thanks, Bagal ...
