> DAG doesn't take the last value of XCOM
> ---------------------------------------
>
> Key: AIRFLOW-5295
> URL: https://issues.apache.org/jira/browse/AIRFLOW-5295
> Project: Apache Airflow
> Issue Type: Bug
> Components: DAG
> Affects Versions: 1.8.0, 1.10.3
> Reporter: Pierrick Boitel
> Priority: Minor
>
> I have sometimes failure on my DAG and need to re-run some tasks. Some of
> these emits a new value for a XCOM, but when following tasks runs, they
> generally takes the old value for this XCOM (although the value is good in
> Airflow's database). In order to have the good value, I have to clear my
> tasks several time (more than 10 time sometimes) which is really painfull.
> I suppose that the DAG on the scheduler keeps the value on cache but not sure
> on this. I didn't enable pickking for the JSON too.
