[jira] [Created] (HDDS-5418) Recon doesn't update datanode's hostname

Janus Chow created HDDS-5418:
--------------------------------

             Summary: Recon doesn't update datanode's hostname 
                 Key: HDDS-5418
                 URL: https://issues.apache.org/jira/browse/HDDS-5418
             Project: Apache Ozone
          Issue Type: Bug
            Reporter: Janus Chow
            Assignee: Janus Chow


Currently the "DatanodeDetails" are stored in Recon's local DB. Once a datanode has registered the content of DatanodeDetails won't be changed.

We met a scenario that datanodes' hostname is changed after running a while in Ozone cluster, the hostname in Recon's UI will still show the old hostnames.

This ticket proposes to send "reregisterCommand" to datanodes if the information of the datanode is changed.
