---------------------------------

             Summary: Add iterator support to INodesInPath
                 Key: HDFS-5875
                 URL: https://issues.apache.org/jira/browse/HDFS-5875
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: namenode
    Affects Versions: 2.0.0-alpha, 3.0.0
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


"Resolve as you go" inode iteration will help with the implementation of alternative locking schemes.  It will also be the pre-cursor for resolving paths once and only once per operation, as opposed to ~3 times/call.

This is an incremental and compatible change for IIP that does not break existing callers.
