steveloughran opened a new pull request, #4729:
URL: https://github.com/apache/hadoop/pull/4729
New trash policies, and a schema specific trash policy set by
fs.SCHEMA.trash.policy.
This lets clusters declare different policies for different stores
in the same cluster.
ResilientTrashPolicy: for abfs with rename failure resilience
DeleteFilesTrashPolicy: for versioned s3 buckets; delete the files.

> ABFS: add resilient trash policy

> Key: HADOOP-18013
> URL: https://issues.apache.org/jira/browse/HADOOP-18013
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/azure
> Affects Versions: 3.3.2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
>
> Add a custom TrashPolicy for azure which
> * is patched in to the config automatically if "fs.trash.classname" is unset
> * checks the source for existing at all before trying anything
> * considers itself enabled even if the trash interval is 0
> * if interval is 0, just does a delete (issue: what about 90s timeouts)
> * downgrades exceptions/failures during rename. If anything is raised and the
> source dir isn't there, all is good.
