This jira is created to support regex based mount point in Inode Tree. We noticed that mount point only support fixed target path. However, we might have user cases when target needs to refer some fields from source. e.g. We might want a mapping of /cluster1/user1 => /cluster1-dc1/user-nn-user1, we want to refer `cluster` and `user` field in source to construct target. It's impossible to archive this with current link type. Though we could set one-to-one mapping, the mount table would become bloated if we have thousands of users. Besides, a regex mapping would empower us more flexibility. So we are going to build a regex based mount point which target could refer groups from src regex mapping. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
