----------------------------
Hi [~jeagles]
Thanks for sharing the details. Could you share any information on why this
Jira has remained unresolved for so long?
It looks like the patch broke some tests, is there something blocking the patch?

> There is a race where a downstream task that is running into fetch failures
> due to bad output from the upstream task can continue to blame itself for the
> failure before the AM can do a re-run of the upstream offending task and fix
> the fetch failure. This causes the DAG to fail even if a single node fails.
