Description

Webhdfs assumes that SPNEGO's AuthenticationException is always fatal. The exception is thrown if authentication truly fails due to bad credentials, but it's also thrown when the auth token expires after 10h. The retry policies are short-circuited and the fs becomes unusable which is unsuitable for long running processes/daemons.
