Once HDFS-11644 goes in, we'll have a clean way of querying for stream capabilities. We should redo the check in the Balancer introduced in HDFS-11643 to query the capabilities.
Thanks Andrew for review the patch and commit!
SUCCESS: Integrated in Jenkins build Hadoop-trunk-Commit #11726 (See https://builds.apache.org/job/Hadoop-trunk-Commit/11726/)
