Chris Nauroth commented on HADOOP-11262:
----------------------------------------

bq. you shouldn't have to set the s3a.impl file; it should instead go into 
core-default.xml

I've been thinking that we really ought to have {{ServiceLoader}} support for 
{{AbstractFileSystem}}, so that S3A and others can register themselves in their 
jar manifest instead of the configuration files, just like {{FileSystem}}.  I 
filed HADOOP-11527 for this.

No need to hold up the work happening here waiting for it though.  This is just 
FYI.
