Stephen O'Donnell commented on HDDS-2197:
-----------------------------------------
The current topology command prints details in the format:
{code:java}
State = HEALTHY
IpAddress(hostName) networkLocation
IpAddress(hostName) networkLocation
IpAddress(hostName) networkLocation
State = STALE
...
State = DEAD
... {code}
Alternatively, it prints the details ordered by network location
{code:java}
State = HEALTHY
Location: somelocation
ipAddress(hostName)
ipAddress(hostName)
ipAddress(hostName)
Location: otherlocation
ipAddress(hostName)
ipAddress(hostName)
ipAddress(hostName)
State = STALE
Location: someLocation
...
...{code}
In this Jira, I propose we simple add the operational state into the existing
output, and keep the ordering and formatting as is:
{code:java}
State = HEALTHY
IpAddress(hostName) IN_SERVICE networkLocation
IpAddress(hostName) IN_SERVICE networkLocation
IpAddress(hostName) DECOMMISSIONING networkLocation
State = STALE
...
State = DEAD
... {code}
Or
{code:java}
State = HEALTHY
Location: somelocation
ipAddress(hostName) IN_SERVICE
ipAddress(hostName) IN_SERVICE
ipAddress(hostName) DECOMMISSIONED
Location: otherlocation
ipAddress(hostName) IN_SERVICE
ipAddress(hostName) IN_MAINTENANE
ipAddress(hostName) IN_SERVIE
State = STALE
Location: someLocation
...
...{code}
