[jira] [Created] (ZEPPELIN-1976) Text Output too large, causing crash

Mathew Wicks created ZEPPELIN-1976:
--------------------------------------

             Summary: Text Output too large, causing crash
                 Key: ZEPPELIN-1976
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1976
             Project: Zeppelin
          Issue Type: Bug
    Affects Versions: 0.6.2
            Reporter: Mathew Wicks
            Priority: Critical


It is very easy to crash the zeppelin web-interface by having a large text output in Spark. Then after restarting zeppelin, the notebook will often be too big to load, causing the user to have to manually edit the note.json.

Example: 

%pyspark
for x in range(1000000):
    print(x)

Potentially we could implement some sort of safeguard against this, like an optional config for byte/character limit on the output, after which the output is truncated.
