Re: Falcon setup - account

[Venkat R <ve...@yahoo.com.INVALID>]

Following the wiki documentation, but not sure what this property name and value means?

# name node principal to talk to config store
*.dfs.namenode.kerberos.principal=nn/_HOST@EXAMPLE.COM
Does this point to the hdfs principal? if so, how can I point falcon to the hdfs user service keytab?

When I try to register the cluster via CLI, I get the following error:
>> Error: Bad Request;Cluster definition missing required namenode credential property: dfs.namenode.kerberos.principal

Thanks
Venkat

I supplied the property name and value in the cluster definition and the CLI seems to like it for now.
