[jira] [Commented] (HDFS-17632) RBF: Support listOpenFiles for routers
[ https://issues.apache.org/jira/browse/HDFS-17632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17885289#comment-17885289 ]

URL: https://github.com/apache/hadoop/pull/7075
### Description of PR
Routers don't have support for `listOpenFiles` yet. Single destination paths are straightforward. Multi destination paths are joined; entries with inodeId > min(max(entry inodeIds)) are ignored to get a consistent prevId for the iterator.
### How was this patch tested?
UTs.
