-------------------------------------
Summary: Allow PrestoHook to retry on failure for certain Exception
Key: AIRFLOW-1481
URL: https://issues.apache.org/jira/browse/AIRFLOW-1481
Project: Apache Airflow
Issue Type: Improvement
Reporter: Alice Berard
Assignee: Alice Berard
Given some instability on the Presto cluster, we are often seeing tasks failing
just because they couldn't communicate with the remote host.
This improvement allows to check for the Exception returned and retry with
exponential backoff without having these retries count as an Airflow retry.
