## What changes were proposed in this pull request? Currently, cancelling a statement on an interactive session only cancels the jobs running on Spark executors but anything running on the Driver keeps running and keeps the session busy. This can be seen by running a sleep in code and running something immediately after cancelling it. This change fixes the cancellation of such tasks for Scala and Python interpreters. https://issues.apache.org/jira/projects/LIVY/issues/LIVY-786 ## How was this patch tested? Tested manually on local setup. Sequence of steps followed: For Python: `curl localhost:8998/sessions/0/statements -X POST -H 'Content-Type: application/json' -d '{"code":"import time\ntime.sleep(60)"}' curl -X POST localhost:8998/sessions/0/statements/0/cancel curl localhost:8998/sessions/0/statements -X POST -H 'Content-Type: application/json' -d '{"code":"print(\"hello\")"}'` The result of second statement was available immediately, meaning that the repl was free. For Scala: `curl localhost:8998/sessions/0/statements -X POST -H 'Content-Type: application/json' -d '{"code":"Thread.sleep(60000)", "kind":"scala"}' curl -X POST localhost:8998/sessions/0/statements/2/cancel curl localhost:8998/sessions/0/statements -X POST -H 'Content-Type: application/json' -d '{"code":"val a=1", "kind":"scala"}'` Similar result seen as above. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
