Yunseong Hwang created ZEPPELIN-5981:
----------------------------------------
Summary: Cannot cancel paragraph
Key: ZEPPELIN-5981
URL: https://issues.apache.org/jira/browse/ZEPPELIN-5981
Project: Zeppelin
Issue Type: Bug
Affects Versions: 0.11.0
Reporter: Yunseong Hwang
Inside an open zeppelin notebook, after running a paragraph by clicking the
play icon button, canceling the running paragraph by clicking the pause icon
button (or the Ctrl+Option+C shortcut) does not interrupt the running process
and cancel the paragraph.
I've checked that CANCEL_PARAGRAPH message gets well passed through the
websocket connection but server was somehow completely ignoring the message.
After some more investigation, I've found that the reason for that was the
Paragraph's jobAbort() method, which does nothing due to the null interpreter
member.
