Review comment:
this is really brittle design. It will only work for one specific store
and contains the assumption that the store always returns the string
"AuthorizationPermissionMismatch" on an error. If the abfs store *ever* changed
that string everything will break.
* That abfs exception also includes a status code, 403, which is what should
really be used as the signal.
* Other stores return AccessDeniedException. Has anyone considered filing a
hadoop bug asking for translation of rest exceptions with 403s into those? I am
reasonably confident nobody is going reject PRs there.
