Subject [jira] [Created] (HDFS-14268) RBF: Fix the location of the DNs in getDatanodeReport()
Date Tue, 12 Feb 2019 21:10:00 GMT
Íñigo Goiri created HDFS-14268:
----------------------------------

             Summary: RBF: Fix the location of the DNs in getDatanodeReport()
                 Key: HDFS-14268
                 URL: https://issues.apache.org/jira/browse/HDFS-14268
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Íñigo Goiri
            Assignee: Íñigo Goiri


When getting all the DNs in the federation, the Router queries each of the subclusters and
aggregates them assigning the subcluster id to the location. This query uses a {{HashSet}}
which provides a "random" order for the results.
