> FileContext.getLocalFSFileContext() instantiates a FileContext object upon
> the first call to it, and for all subsequent calls returns back that instance
> (a static localFsSingleton object). With security turned on, this causes some
> hard-to-debug situations when that fileContext is used for doing HDFS
> operations. This is because the UserGroupInformation is stored when a
> FileContext is instantiated. If the process in question wishes to use
> different UserGroupInformation objects for different file system operations
> (where the corresponding FileContext objects are obtained via calls to
> FileContext.getLocalFSFileContext()), it doesn't work.
