[jira] [Created] (HDFS-6082) List all NNs with state

Rafal Wojdyla created HDFS-6082:
-----------------------------------

             Summary: List all NNs with state
                 Key: HDFS-6082
                 URL: https://issues.apache.org/jira/browse/HDFS-6082
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: ha, namenode
            Reporter: Rafal Wojdyla


HAAdmin let's you determine state of *given* service. It would be nice to have a call to determine states of all Namenodes (services?), something like:

hdfs haadmin -getServicesState

And the output would be:
hostname | state

This can be implemented at HAAdmin level - for all HA services or at DFSHAAdmin level - for Namenode HA only.
