jupyter 抛出错误:socket.gaierror:[errno -2] 名称或服务未知

Question

我在 AWS EMR 上运行一个 pyspark 集群，并将 Jupyter 用于 pyspark 驱动程序。最近，脚本失败了。Jupiter 无法启动服务器。我用conda install jupyter安装并从sudo initctl start jupyter开始.群集运行良好。以下是服务器的配置值。

# jupyter configs
mkdir -p ~/.jupyter
touch ls ~/.jupyter/jupyter_notebook_config.py
HASHED_PASSWORD=$(python -c "from notebook.auth import passwd; 
print(passwd('$JUPYTER_PASSWORD'))")
echo "c.NotebookApp.password = u'$HASHED_PASSWORD'" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.open_browser = False" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.ip = '*'" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.notebook_dir = '/mnt/$BUCKET/$FOLDER'" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.ContentsManager.checkpoints_kwargs = {'root_dir': '.checkpoints'}" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.port = 8080" >> ~/.jupyter/jupyter_notebook_config.py

Answer 1

我发现在更新到 jupyter 5.7 之后。我不得不修改配置参数。改变

echo "c.NotebookApp.ip = '*'" >> ~/.jupyter/jupyter_notebook_config.py

自

echo "c.NotebookApp.ip = '0.0.0.0'" >> ~/.jupyter/jupyter_notebook_config.py
