-------------------------------
Summary: For recovered DAGs that are completed or non-recoverable
- fix needed for ATS/History events
Key: TEZ-2925
URL: https://issues.apache.org/jira/browse/TEZ-2925
Project: Apache Tez
Issue Type: Sub-task
Reporter: Bikas Saha
We have recovered the dag and its completed or non-recoverable (hence failed).
For such cases, its not clear what the history state is. For completed dags,
history events may not have been fully sent. For non-recoverable dags history
events may be incomplete because the DAG may have been running.
This needs a solution because history dependent things like UI may end up
showing the DAG as running forever.
One potential solution could be to send a DAG summary data to history with
final state for such dags.
