该错误是远程诊断没有配置导致的,不是必须的服务,直接删除即可.
The Telemetry Publushing Service is not a necessary component of a Cloudera cluster deploy - it is to supplement an add-on service called "Workload Experience Manager or Workload XM".
You can safely delete the service and it will not affect cluster operations
If Workload XM is a functionality you wish to leverage then you will need to take a couple steps to enable the Telemetry Publisher to send telemetry to Cloudera.
Here is the Guide I Followed:
https://www.cloudera.com/documentation/wxm/latest/topics/wxm_setup.html
Step 1. Get Altus Credentials
Step 2. Add Altus Credentials to Cloudera Manager
Step 3. Add the Telemetry Publisher Service Role
Basically you need to log into your Altus account and generate a key pair for WXM to leverage - you will then need to add this account in Cloudera Manager as an external account under the altus tab. That can be done here. https://altus.cloudera.com/wxm/home.html#/
Next in Cloudera Manager:
Administration -> External Accounts -> click "Altus Credentials" tab and add the account.
You may need to configure the account as your Altus account in Administration -> Settings -> "Telemetry Altus Account"
The docs don't say this but I had to restart Cloudera Manager to get this setting to take effect - I could not start the Telemetry Publisher until after I restarted Cloudera Manager
To access Workload XM, perform the following steps:
Log in to the Workload XM console: wxm.cloudera.com/
