-------------------------------------
> S3A to warn or fail if S3Guard is disabled
> ------------------------------------------
>
> Key: HADOOP-16484
> URL: https://issues.apache.org/jira/browse/HADOOP-16484
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.2.0
> Reporter: Steve Loughran
> Assignee: Gabor Bota
> Priority: Minor
> Fix For: 3.3.0
>
>
> A seemingly recurrent problem with s3guard is "people who think S3Guard is
> turned on but really it isn't"
> It's not immediately obvious this is the case, and the fact S3Guard is off
> tends to surface after some intermittent failure has actually been detected.
> Propose: add a configuration parameter which chooses what to do when an S3A
> FS is instantiated without S3Guard
> * silent : today; do nothing.
> * status: give s3guard on/off status
> * inform: log FS is instantiated without s3guard
> * warn: Warn that data may be at risk in workflows
> * fail
> deployments could then choose which level of reaction they want. I'd make the
> default "inform" for now; any on-prem object store deployment should switch
> to silent, and if you really want strictness, fail is the ultimate option
