Aaron T. Myers reassigned HDFS-6440: ------------------------------------ Assignee: Jesse Yates Thanks a lot for all of your work on this so far, Jesse. Assigning this JIRA to you. > Support more than 2 NameNodes > ----------------------------- > > Key: HDFS-6440 > URL: https://issues.apache.org/jira/browse/HDFS-6440 > Project: Hadoop HDFS > Issue Type: New Feature > Components: auto-failover, ha, namenode > Affects Versions: 2.4.0 > Reporter: Jesse Yates > Assignee: Jesse Yates > Attachments: hdfs-6440-cdh-4.5-full.patch > > > Most of the work is already done to support more than 2 NameNodes (one > active, one standby). This would be the last bit to support running multiple > _standby_ NameNodes; one of the standbys should be available for fail-over. > Mostly, this is a matter of updating how we parse configurations, some > complexity around managing the checkpointing, and updating a whole lot of > tests. -- This message was sent by Atlassian JIRA (v6.2#6252)
