Alejandro Abdelnur commented on HADOOP-9041:
--------------------------------------------

Yanbo Liang, the change in the patch looks like it would not change the current 
behavior. Still I'm failing to see why a call to how 
FileSystem.loadFileSystems() gets to invoke FsUrlStreamHandlerFactory. AFAIK, 
this could happen only if the default constructor of the filesystem tries to 
create a URL with a FS scheme. Which FileSystem impl you've found it is doing 
that?

> More information is there: https://jira.springsource.org/browse/SHDP-111
> Referenced source code from example is: 
> https://github.com/SpringSource/spring-hadoop/blob/master/src/main/java/org/springframework/data/hadoop/configuration/ConfigurationFactoryBean.java
> from isolating that cause it looks like if you register: 
> org.apache.hadoop.fs.FsUrlStreamHandlerFactory before calling 
> FileSystem.loadFileSystems() then it goes into infinite loop.
