Aaron T. Myers commented on HDFS-3571:
--------------------------------------
Patch largely looks good to me. One little comment:
# {{"Image transfer servlet at " + url + " failed with status code"}} - The
thing at the other end of the URLLog isn't _necessarily_ an image transfer
servlet, right? Might just want to say "server", as you do later in the method
if you don't get a content length header.
+1 once this is addressed.

> In order to start up from remote edits storage (like the JournalNodes of
> HDFS-3077), the NN needs to be able to load edits from a URL, instead of just
> local disk. This JIRA extends EditLogFileInputStream to be able to use a URL
> reference in addition to the current File reference.
