avijayanhwx opened a new pull request #569: HDDS-3209. Recon should persist Node metadata. URL: https://github.com/apache/hadoop-ozone/pull/569 ## What changes were proposed in this pull request? SCM does not persist Node metadata in a persistent store like RocksDB. It is needed in Recon since its UI will be a management console, and should be able to withstand DNs shutting down while it is not running. Whenever Recon starts up, it can display all registered Nodes from this DB (even before Heartbeats) and then gradually update state based on heartbeats. In addition to the above, the patch also contains the following. - Review comments from https://github.com/apache/hadoop-ozone/pull/546 addressed. - Fixed issue in ReconContainerReportHandler. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-3029 ## How was this patch tested? Manually tested. Added unit test.
