Colin Patrick McCabe commented on HDFS-6013: -------------------------------------------- Looks good overall. If we're going to expose the output of {{RollingUpgradeInfo#toString}}, in JMX, then it would be nice to add a comment to the {{RollingUpgradeInfo#toString}} function saying that its output can't be changed without potentially causing monitoring tool incompatibilities. Alternately, we could just avoid this function and create the string inside getRollingUpgradeStatus. > add rollingUpgrade information to latest UI > -------------------------------------------- > > Key: HDFS-6013 > URL: https://issues.apache.org/jira/browse/HDFS-6013 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: namenode > Reporter: Vinayakumar B > Assignee: Vinayakumar B > Attachments: HDFS-6013.patch > > > Rolling Upgrade information should be shown in the latest NameNode UI. > For this RollingUpgrade information should be exposed as jmx bean. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
