> The Hadoop token service loading (identifiers, renewers...) works provided there's no
problems loading any registered implementation. If there's a classloading or classcasting
problem, the exception raised will stop all token support working; possibly the application
not starting.
> This matters for S3A/HADOOP-14556 as things may not load if aws-sdk isn't on the classpath.
It probably lurks in the wasb/abfs support too, but things have worked there because the installations
with DT support there have always had correctly set up classpaths.
> Fix: do what we did for the FS service loader. Catch failures to instantiate a service
provider impl and skip it
