>                 URL: https://issues.apache.org/jira/browse/HDFS-6082
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: ha, namenode
>            Reporter: Rafal Wojdyla
>            Priority: Minor

> 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 -ns foobar -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.
