----------------------------------------
Summary: 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: 1.10.3, 1.8.0
Reporter: Pierrick Boitel
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.
