Enabling Key Trustee Keys
Accessing files from HDFS with Telemetry Publisher when your access keys are stored in the Cloudera Key Trustee Server.
By default, when keys are stored in the Key Trustee Server the HDFS user for Telemetry Publisher (hdfs) does not have permission to access files.
To enable access to your files in HDFS, the Telemetry Publisher user must belong to the user groups that authenticate user access for the Job History Server and the Spark History Server. For example, if the hadoop user group authenticates access for the Job History Server and the spark user group authenticates access for the Spark History Server, then the Telemetry Publisher user must belong to the hadoop group and the spark group to download files from HDFS.
