Hi @ovolmar did you find a solution please? I am facing the same problem : TASK [cloudera.cluster.cluster : Fail because of unsuccessful cluster template import] *** fatal: [ip]: FAILED! => {"changed": false, "msg": "Cluster template import failed. Result message: Cannot deserialize instance of java.lang.String out of START_ARRAY token\n at [Source: (org.apache.cxf.transport.http.AbstractHTTPDestination$1); line: 1, column: 1361] (through reference chain: com.cloudera.api.model.ApiClusterTemplate[\"instantiator\"]->com.cloudera.api.model.ApiClusterTemplateInstantiator[\"variables\"]->java.util.ArrayList[12]->com.cloudera.api.model.ApiClusterTemplateVariable[\"value\"])\n"}

I had the same problem, the issue was in the definition.yml when setting multiple disks in the dfs_data_dir_list. You cannot use the array/list format like:

 DATANODE:
          dfs_data_dir_list:
            - /dfs/disk1
            - /dfs/disk2
            - /dfs/disk3

I have used the comma separated paths in one line instead, it worked afterwards. for example:

 DATANODE:
          dfs_data_dir_list: /dfs/dn1,/dfs/dn2,/dfs/dn3,/dfs/dn4

The error mesage itself Cannot deserialize instance of java.lang.String out of START_ARRAY tells you that CM cannot read/parse the array of paths, it is all being imported in the first input field of dfs.data.data.dir config, which does not accept array. hope that helped :)
