Subject [jira] [Updated] (HDFS-8444) Erasure Coding: fix cannot rename a zone dir
Date Tue, 02 Jun 2015 06:24:17 GMT

Walter Su updated HDFS-8444:
----------------------------
    Attachment: HDFS-8444-HDFS-7285.002.patch

I was trying not to deserialize when it's a rename under non-ec dir. It's a tiny tiny performance
improvement. I agree with your approach. The code is cleaner. Uploaded 002 patch.
