cdp-doctor salt ping
Scope
The cdp-doctor salt ping command is used to verify connectivity between the Salt master and all Salt minions within a Cloudera deployment. It ensures that the Salt orchestration framework, responsible for remote execution and configuration management in CDP, is functioning correctly across all nodes.
This command provides a quick way to confirm that each host is reachable, responsive, and properly registered with the Salt master.
- Salt Master - Minion Communication: Ensures that the Salt master can communicate successfully with each node (minion).
- Minion Responsiveness: Confirms that the minion service is running and responding to pings.
- Network and Authentication Health: Validates network connectivity and hostname resolution between nodes.
Use Case
- Performing cluster health or connectivity validation.
- Diagnosing issues where nodes are not receiving configuration updates or orchestration commands.
- Verifying Salt service health after deployment or during troubleshooting.
Sample Output
Running the cdp-doctor salt ping command displays the following output:
+--------------------------------------------------------------------------+--------+
| Host | Status |

| default-aws-aw-dl-master0.cloudera.site | [OK] |
| default-aws-aw-dl-idbroker0.cloudera.site | [OK] |
+----------------------------------------------------------------+--------+
