Steve Loughran commented on HADOOP-13059:
-----------------------------------------
the new lambda-operator retry logic will retry in init(), but it'll give up
there if things aren't working. that way, you're allowed a brief bit of failure
with the same retry logic as other idempotent calls get.
> S3a over-reacts to potentially transient network problems in its init() logic

> Key: HADOOP-13059
> URL: https://issues.apache.org/jira/browse/HADOOP-13059
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran

> If there's a reason for s3a not being able to connect to AWS, then the
> constructor fails, even if this is a potentially transient event.
> This happens because the code to check for a bucket existing will relay the
> exceptions.
> The constructor should catch IOEs against the remote FS, downgrade to warn
> and let the code continue; it may fail later, but it may also recover.
