[jira] [Updated] (HDFS-9004) Add upgrade domain to DatanodeInfo

     [ https://issues.apache.org/jira/browse/HDFS-9004?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ming Ma updated HDFS-9004:
--------------------------
    Attachment: HDFS-9004.patch

Here is the initial patch. Given the JMX output and metasave output have changed to include upgrade domain info, it seems we should mark change incompatible.

> As part of upgrade domain feature, we first need to add upgrade domain string to {{DatanodeInfo}}. It includes things like:
> * Add a new field to DatanodeInfo.
> * Modify protobuf for DatanodeInfo.
> * Update DatanodeInfo.getDatanodeReport to include upgrade domain.
