             Summary: Umbrella jira for improved HDFS rolling upgrades
                 Key: HDFS-5535
                 URL: https://issues.apache.org/jira/browse/HDFS-5535
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: datanode, ha, hdfs-client, namenode
    Affects Versions: 2.2.0, 3.0.0
            Reporter: Nathan Roberts

In order to roll a new HDFS release through a large cluster quickly and safely, a few enhancements
are needed in HDFS. An initial High level design document will be attached to this jira, and
sub-jiras will itemize the individual tasks.
