             Summary: Make DataNode reconfiguable
                 Key: HDFS-6727
                 URL: https://issues.apache.org/jira/browse/HDFS-6727
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode
    Affects Versions: 2.4.1
            Reporter: Lei (Eddy) Xu

HDFS-1362 requires DataNode to reload configuration file during the runtime, so that DN can change the data volumes dynamically. This JIRA reuses the reconfiguration framework introduced by HADOOP-7001 to enable DN to reconfigure at runtime.
