Zhang Wei reassigned HDFS-8500: ------------------------------- Assignee: Zhang Wei > Improve refreshNodes in DFSAdmin to support hdfs federation > ----------------------------------------------------------- > > Key: HDFS-8500 > URL: https://issues.apache.org/jira/browse/HDFS-8500 > Project: Hadoop HDFS > Issue Type: Improvement > Components: federation > Affects Versions: 2.7.0 > Reporter: Zhang Wei > Assignee: Zhang Wei > Priority: Minor > Labels: decommission, federation, refreshnodes > > In hdfs federated cluster, we find the dfsadmin command "hdfs dfsadmin > -refreshNodes" can only refresh the nameservice (or namenode) which > configured in fs.defaultFS. The other nameservices configured in > hdfs-site.xml can't be refreshed unless changing the fs.defaultFS value and > run this command again. I think we need additional parameters as following to > give a convenient way: > [-a] fresh all namenodes configured in hdfs-site.xml. > [-ns <nameserviceId>] specify a nameservice to refresh. > [host:ipc_port] specify a nn to refresh. > please give your opinions.
