------------------------------------
Summary: Cancelling statement does not work
Key: LIVY-786
URL: https://issues.apache.org/jira/browse/LIVY-786
Project: Livy
Issue Type: Bug
Components: Core
Affects Versions: 0.6.0
Environment: emr-5.29.0
Reporter: Quentin Lemaire
Hi!
I am running into troubles when trying to cancel a statement during an
interactive session.
The code I am running is:
{code:java}
Thread.sleep(600000)
val r = 1 + 1
{code}
When I cancel the statement, I see the status of the statement changing to
"Cancelling" in the Livy UI. After 30s (I left the default timeout), it changes
to "Cancelled" and I see "Failed to cancel statement 1" in the logs. The
session is still "Busy" and it finishes to run the code. Therefore, the
cancellation didn't work and I can even see the result "r: Int = 2" after the
sleep.
Do you have any idea why it doesn't manage to cancel the statement (the code I
am running is pretty basic). I didn't manage to find other information/logs on
why the cancellation did not work correctly.
The only solution I found to cancel such a statement is to kill the session.
Thanks!
