Maziyar PANAHI created ZEPPELIN-3847:
Summary: Duplicate results in notebooks
Key: ZEPPELIN-3847
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3847
Project: Zeppelin
Issue Type: Bug
Affects Versions: 0.8.0
Reporter: Maziyar PANAHI

After upgrading to Zeppelin 0.8.0 with the same tech stack behind it, I start
noticing after a while working with any notebooks (small or large), the
notebook becomes unresponsive for few seconds where I can't scroll then it
produces duplicate results for all the executed paragraphs.
Not sure if the page becomes unresponsive due to duplicating all the results
from all the paragraphs or it is for another reason, but I am sure it should be
related to copying all those results twice in the page.
NOTE: If I refresh the page, there is no duplicate and there is only one result
for each paragraph. This only happens while the notebook is open.
I have one idea, to reproduce this you can simply disconnect from the internet
(if the zeppelin is hosted remotely). WebSocket keeps trying to connect,
re-connect the internet and you see immediately the results being duplicated.
