----------------------------------
Summary: Rename does not need to re-solve destination
Key: HDFS-10779
URL: https://issues.apache.org/jira/browse/HDFS-10779
Project: Hadoop HDFS
Issue Type: Sub-task
Components: hdfs
Reporter: Daryn Sharp
Assignee: Daryn Sharp
Rename uses {{FSDirectory.isDir(String)}} to determine if the destination is a
directory. This dissect the path, creates an IIP, checks if the last inode is
a directory. The rename operations already have the IIP and can check it
directly.
