[jira] [Created] (AMBARI-2916) DataNode cannot be started on a host that was added post-install

Nate Cole created AMBARI-2916:
---------------------------------

             Summary: DataNode cannot be started on a host that was added post-install
                 Key: AMBARI-2916
                 URL: https://issues.apache.org/jira/browse/AMBARI-2916
             Project: Ambari
          Issue Type: Task
          Components: client
    Affects Versions: 1.4.0
            Reporter: Nate Cole
            Assignee: Nate Cole
             Fix For: 1.4.0


The properties for hdfs-site/dfs.hosts and hdfs-site/dfs.hosts.exclude are generated on install (and config change).  When creating a datanode post-install, the files get updated, but requires a restart of the NN in order to for it to read the new entry.  In a normal install, DN should be able to register themselves without any restart.
