cloudera api Unknown configuration attribute 'dfs_data_dir_list'

[#1]

hi,

I am working with python and cm_api. I got the following response when I execute my script. I copied and paste the code from the cloudera blog

This is the code:

hdfs_service_config = {
  'dfs_replication': 2,
}
nn_config = {
  'dfs_name_dir_list': '/dfs/nn',
  'dfs_namenode_handler_count': 30,
}
snn_config = {
  'fs_checkpoint_dir_list': '/dfs/snn',
}
dn_config = {
  'dfs_data_dir_list': '/dfs/dn1,/dfs/dn2,/dfs/dn3',
  'dfs_datanode_failed_volumes_tolerated': 1,
}
hdfs.update_config(
    svc_config=hdfs_service_config,
    NAMENODE=nn_config,
    SECONDARYNAMENODE=snn_config,
    DATANODE=dn_config)

cm-api (14.0.0)

Any ideas?

I got a solution.

for group in dn_groups:
group.update_config({'dfs_data_dir_list': '/dfs'})

Thank you for sharing your solution. I do need to clarify about the code from the blog. Which article was it from? Also, are you saying there was an error with the code or that you were having difficulty changing it to match your conditions?

Hello,

Is this article: http://blog.cloudera.com/blog/2012/09/automating-your-cluster-with-cloudera-manager-api/

In the step3 ("configuring HDFS") I just get errors and errors.

My conditions matched ok with this new configuration.

Any question let me know
