Weichen Xu created SPARK-28483:
----------------------------------
Summary: Canceling a spark job using barrier mode but tasks still
being printing messages
Key: SPARK-28483
URL: https://issues.apache.org/jira/browse/SPARK-28483
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.4.3
Reporter: Weichen Xu
Reproduce code:
{code:java}
import time
from pyspark import BarrierTaskContext
n = 4
def task(x):
context = BarrierTaskContext.get()
this = next(x)
if (this % 2 == 0):
time.sleep(10000)
context.barrier()
return []
sc.setLogLevel("INFO")
sc.parallelize(list(range(n)), n).barrier().mapPartitions(task).collect(){code}
Get logging like:
```
