Reopening and closing this instead as a dup of HADOOP-13786 as I don't find any patch for this JIRA in the source-code. Please revert back if this is incorrect.
> S3A to support custom retry policies; failfast on unknown host
> --------------------------------------------------------------
>
> Key: HADOOP-13205
> URL: https://issues.apache.org/jira/browse/HADOOP-13205
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Fix For: 3.1.0
>
>
> 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.
