That part of change is not relevant anymore since that part of code was removed by HDFS-6005. > Document new commands and parameters for improved rolling upgrades > ------------------------------------------------------------------ > > Key: HDFS-5778 > URL: https://issues.apache.org/jira/browse/HDFS-5778 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: documentation > Affects Versions: HDFS-5535 (Rolling upgrades) > Reporter: Akira AJISAKA > Assignee: Tsz Wo (Nicholas), SZE > Attachments: h5778_20140220.patch, h5778_20140221.patch > > > "hdfs dfsadmin -rollingUpgrade" command was newly added in HDFS-5752, and > some other commands and parameters will be added in the future.
