Jane Chen commented on HADOOP-7549:
-----------------------------------
Hi Alejandro,
I was calling FileSystem.get(URI, conf, user) from C++ code through JNI. After
upgrading to 2.0, this call is giving me "java.util.ServiceConfigurationError:
org.apache.hadoop.fs.FileSystem: Provider org.apache.hadoop.fs.LocalFileSystem
not found" error. It doesn't seem to be a classpath issue, since I can
instantiate the class with no problem. I'd like to know whether you have any
insight on this.
Also I read in the bug that there's a configuration to disable loading through
ServiceLoader. I'd like to try that, and would appreciate if you could let me
know what's the proper way to do that.
Thanks,
Jane

> 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).
