             Summary: [Observer Node] Balancer should submit getBlocks to Observer Node when possible
                 Key: HDFS-14979
                 URL: https://issues.apache.org/jira/browse/HDFS-14979
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: balancer & mover, hdfs
            Reporter: Erik Krogen
            Assignee: Erik Krogen


In HDFS-14162, we made it so that the Balancer could function when {{ObserverReadProxyProvider}} was in use. However, the Balancer would still read from the active NameNode, because {{getBlocks}} wasn't annotated as {{@ReadOnly}}. This task is to enable the Balancer to actually read from the Observer Node to alleviate load from the active NameNode.
