Axel Van Damme created ZEPPELIN-5988:
----------------------------------------
Summary: Bokeh output in IPySpark is not in correct format
Key: ZEPPELIN-5988
URL: https://issues.apache.org/jira/browse/ZEPPELIN-5988
Project: Zeppelin
Issue Type: Bug
Components: pySpark
Affects Versions: 0.10.1
Environment: Latest Apache Zeppelin compiled from sources
Reporter: Axel Van Damme
I'm using the latest Zeppelin version compile from the source code (Version
0.11.0-SNAPSHOT)
I'm facing the issue explained in
https://issues.apache.org/jira/browse/ZEPPELIN-4771
It means that when running a simple Bokeh code with %ipyspark (or even with
%python.ipython)interpreter, the text output is not correctly formatted.
You can try for example with this example where I did a on purpose typo:
%ipyspark
import numpy as np
from bokeh.plotting import figure, show, output_notebook
output_notebook()
x = np.linspace(-6, 6, 500)
y = 8*np.sin(x)*np.sinc(x)
p = figure(width=800, height=300, title="", tools="",
toolbar_location=None, match_aspect=True)
p.line(x, ey, color="navy", alpha=0.4, line_width=4)
show(p)
then the output is scrabbled like this:
