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-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
