[ https://issues.apache.org/jira/browse/HDFS-12555?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16201505#comment-16201505 ] luoge123 commented on HDFS-12555: - In current federation function, if the /user directory has been configured as follows : fs.viewfs.mounttable.nsX.link./user hdfs://nn1:8020/user then, we can't add the follow /user/hive configuration to core-site.xml any more. fs.viewfs.mounttable.nsX.link./user/hive hdfs://nn2:8020/user/hive My improvement is that the two configuration items all exist in core-site.xml at same time. After support this configuration, we need copy data from hdfs://nn1:8020/user/hive to hdfs://nn2:8020/user/hive, fastcp or distcp tools can help us. And then we can delete hdfs://nn1:8020/user/hive. After we done this, the meta data in /user directory except /user/hive all manager by nn1, and read and write requests are send to nn1. The meta data for /user/hive manager by nn2, read and write requests for /user/hive are send to nn2. I'm not sure this explanation could answer your question or not, if you have any questions, please fell free to contact me. > HDFS federation should support configure secondary directory > - > > Key: HDFS-12555 > URL: https://issues.apache.org/jira/browse/HDFS-12555 > Project: Hadoop HDFS > Issue Type: Improvement > Components: federation > Environment: 2.6.0-cdh5.10.0 >Reporter: luoge123 > Fix For: 2.6.0 > > Attachments: HDFS-12555.001.patch > > > HDFS federation support multiple namenodes horizontally scales the file > system namespace.

After your fix /user/hive will move to new namenode right(nn2)? On the new namenode the old files will not be there right? So, this should be a one time setup thing.
