[ https://issues.apache.org/jira/browse/HDFS-5875?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Daryn Sharp updated HDFS-5875: -- Attachment: HDFS-5875.patch Adds standard iterator support. The iterator is a nested class so it can fill-in the existing data members in IIP with minimal change (somewhat gross). Given how subtle bugs in this code region cause nearly un-debuggable test failures, I wanted to disturb as little code as possible. Overall, it's not the prettiest change, but I intend to iteratively - no pun intended - improve it. I removed the (what appears to be) pre-mature optimization for capturing 1 inode. This is used by extraneous calls that unnecessarily re-resolve the whole path just to get the last inode. These will soon go away when paths are resolved once and only once.
