sodonnel opened a new pull request #37: HDDS-2197 Extend SCMCLI Topology command to print node Operational States URL: https://github.com/apache/hadoop-ozone/pull/37 The scmcli topology command only consider the node health (healthy, stale or dead). With decommission and maintenance stages, we need to also consider the operational states and display them with this command. The current topology command prints details in the format: ``` State = HEALTHY IpAddress(hostName) networkLocation IpAddress(hostName) networkLocation IpAddress(hostName) networkLocation State = STALE ... State = DEAD ... ``` Alternatively, it prints the details ordered by network location ``` State = HEALTHY Location: somelocation ipAddress(hostName) ipAddress(hostName) ipAddress(hostName) Location: otherlocation ipAddress(hostName) ipAddress(hostName) ipAddress(hostName) State = STALE Location: someLocation ... ... ``` In this PR, I propose we simple add the operational state into the existing output, and keep the ordering and formatting as is: ``` State = HEALTHY IpAddress(hostName) IN_SERVICE networkLocation IpAddress(hostName) IN_SERVICE networkLocation IpAddress(hostName) DECOMMISSIONING networkLocation State = STALE ... State = DEAD ... ``` Or ``` 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 ... ... ```
