> Noticed today that when connections are down, S3A retries on UnknownHostExceptions logging noisily in the process.
> # it should be possible to define or customize retry policies for an FS instance (fail fast, exponential backoff, etc)
> # we may want to explicitly have a fail-fast-if-offline retry policy, catching the common connectivity ones.
> Testing will be fun here.
