DataWorks:Common issues

Data backfill feature overview

Why does group execution for data backfill not work for hourly and minutely nodes?

Why do data backfill instances not run and show a "waiting for time" status after I select a business time?

Why does a data backfill error report that the node runtime is outside the selected business time range?

Why are no data backfill instances generated for a node selected for data backfill?

Why do tasks wait for resources?

Why does a task keep waiting for gateway scheduling resources?

Why does a data integration task always show a 'wait' status?

What is a dry-run?

Why do dry-runs occur?

1. Scenario 1: Dry-run cycle for weekly or monthly instances

2. Scenario 2: Expired instances generated in real time

3. Scenario 3: Instances set to successful

4. Scenario 4: Instance Property Dry-Run

5. Scenario 5: Unselected instances in a temporary workflow

Troubleshoot dry-runs for daily scheduled tasks

What are the conditions that are required for a node to successfully run?

Why is an auto triggered instance not run after its scheduling time arrives?

What do I do if I cannot find the desired auto triggered node on the Cycle Task page in Operation Center?

Why cannot I find even one instance of an auto triggered node?

What do I do if I can find instances of other auto triggered nodes but cannot find even one instance of the desired auto triggered node?

What do I do if the desired auto triggered node has instances but the instances are not run?

What are the conditions that must be met to run a node?

What happens after I freeze or unfreeze an auto triggered node or an auto triggered instance?

Why is a frozen auto triggered node run as scheduled?

Scenario 1: An auto triggered node is successfully run and has operational logs

Scenario 2: An auto triggered node is successfully run but has no operational logs

General reference

• A task configured for auto-rerun does not rerun after it fails and reports the error Task Run Timed Out, Killed by System!!!

• A task fails with the error OSError: [Errno 7] Argument list too long.
