Hari Sekhon updated AMBARI-6706: -------------------------------- Environment: HDP 2.1 & HDP 2.2 (was: HDP 2.1) > Rolling restarts for HA Masters eg HDFS NameNodes > ------------------------------------------------- > > Key: AMBARI-6706 > URL: https://issues.apache.org/jira/browse/AMBARI-6706 > Project: Ambari > Issue Type: Improvement > Affects Versions: 1.6.1, 1.7.0 > Environment: HDP 2.1 & HDP 2.2 > Reporter: Hari Sekhon > > Rolling restarts currently only work for slaves such as Datanodes in Web UI > when doing Service Actions -> Restart Datanodes. When doing a Restart All it > doesn't give any option to do a rolling restart across all components > including masters. > I usually configure HDFS NameNode HA but this means that in Ambari there is > downtime in reconfiguration even with NN HA enabled since it doesn't do > rolling restarts of the NameNodes in order to keep the cluster up. > This is needed to actually make the service really HA including HA during > routine maintenance and reconfiguration. Maybe I could workaround to shut > master components one by one manually but would be nice if Ambari could > support this directly. > Regards, > Hari Sekhon > http://www.linkedin.com/in/harisekhon -- This message was sent by Atlassian JIRA (v6.3.4#6332)
