-------------------------------
Summary: Handling of fetch-failures should consider time spent
producing output
Key: TEZ-3444
URL: https://issues.apache.org/jira/browse/TEZ-3444
Project: Apache Tez
Issue Type: Improvement
Reporter: Jason Lowe
When handling fetch failures and deciding whether the upstream task should be
re-run, we should consider the duration of the upstream task that generated the
data trying to be fetched. If the upstream task ran for a long time then we
may want to retry a bit harder before deciding to re-run. If the upstream task
executed in a few seconds then we should probably re-run the upstream task more
aggressively since that may be cheaper than multiple retries that timeout.
