--------------------------------------
Component/s: (was: HDFS)
> FIleSystem does not honor Configuration.getClassLoader() while loading
> FileSystem implementations

> Key: HDFS-8750

> In FileSystem.loadFileSystems(), at
> https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java#L2652
> a "scheme" -> "FileSystem implementation" map is created from the jars
> available on classpath. It uses Thread.currentThread().getClassLoader() via
> ServiceLoader.load(FileSystem.class)
> Instead, loadFileSystems() should take Configuration as an argument and
> should first check if a classloader is configured in
> configuration.getClassLoader(), if yes then
> ServiceLoader.load(FileSystem.class, configuration.getClassLoader()) should
> be used.
