[jira] Commented: (HADOOP-4395) Reloading FSImage and FSEditLog may
erase user and group information
Posted by "Raghu Angadi (JIRA)" <ji...@apache.org>.

Raghu Angadi commented on HADOOP-4395:
--------------------------------------
I think a considerable part of the reason why this bug got in is lack of javadoc contract for setOwner() methods. Though these are supposed to be hdfs internal, javadoc should have been there. But this comment is too late for this jira I guess.
