Íñigo Goiri commented on HDFS-13478: ------------------------------------ Thanks [~linyiqun] for the comments. After checking, we cannot reuse the membership table as it is updated per Router and the way the heartbeat is done would overwrite everything. For the length, I agree. We can go with [^HDFS-13478.001.patch] which just does the basic wiring and then we can do the RPC checks in another one. We can remove the change for MembershipNamenodeResolver from [^HDFS-13478.001.patch]. > RBF: Decommission subclusters from the federation > ------------------------------------------------- > > Key: HDFS-13478 > URL: https://issues.apache.org/jira/browse/HDFS-13478 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Íñigo Goiri > Assignee: Íñigo Goiri > Priority: Major > Attachments: HDFS-13478.000.patch, HDFS-13478.001.patch > > > We have a subcluster in our federation that is for testing and is > missbehaving.
