[jira] [Created] (AIRFLOW-1481) Allow PrestoHook to retry on failure for certain Exception

Alice Berard created AIRFLOW-1481:
-------------------------------------

             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.
