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 (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
