Subject [jira] [Created] (AIRFLOW-1481) Allow PrestoHook to retry on failure for certain Exception
Date Tue, 01 Aug 2017 20:02:00 GMT
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.
