      Description

      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.
