Tom White commented on HADOOP-7549:
-----------------------------------

+1 This looks good to me. Existing configurations will still work with this 
patch, so there are no compatibility concerns.

> Currently configuring FileSystem implementations must be done by declaring 
> the FileSystem class in the Hadoop configuration files (core-default.xml, 
> ...).
> Using JDK ServiceLoader mechanism this configuration step can be avoided. 
> Adding the JAR file with the additional FileSystem implementation would 
> suffice. 
> This is similar to what is being proposed for compression codecs 
> (HADOOP-7350).
