Steve Loughran commented on HADOOP-16393:
-----------------------------------------
This leads to a fun failure. You can't instantiate a store because its bucket
doesn't exist:

> ---------------------------------------------------------------------
>
> Key: HADOOP-16393
> URL: https://issues.apache.org/jira/browse/HADOOP-16393
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.2.0
> Reporter: Steve Loughran
> Priority: Major
>
> If you call {{s3guard init s3a://name/}} then the custom bucket options of
> fs.s3a.bucket.name are not picked up, instead the global value is used.
> Fix: take the name of the bucket and use that to eval properties and patch
> the config used for the init command.
