Suresh Srinivas commented on HADOOP-7549:
-----------------------------------------
> From a user perpective, just adding a JAR with a new FileSystem is enough to
> use it, no need to set configurations in conf/ or in their APP.
Typically configuration is preset in core-default.xml and users do not need to
change it.
Only frameworks such as mapreduce and raid change it.
> Use JDK ServiceLoader mechanism to find FileSystem implementations

>
> 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).
