--------------------------------------

             Summary: Add a "cluster-info" command to the Flink command line client
                 Key: FLINK-18787
                 URL: https://issues.apache.org/jira/browse/FLINK-18787
             Project: Flink
          Issue Type: New Feature
          Components: Command Line Client
            Reporter: Robert Metzger


It would be useful for users to get access to cluster information from the command line as well.
This could include information accessible via the REST API: number of task managers, running jobs, configuration.
One other bit of information would be the current jobmanager REST endpoint address, as this is difficult to get when running on YARN, with HA etc.
