无法在HDInsight 4.0中创建Jupyter Notebook

Question

我正在使用Azure HDInsight 4.0（Spark 2.4）。当我尝试创建新的Jupyter笔记本（Spark，但PySpark笔记本出现类似错误）时，出现以下错误消息：

Traceback (most recent call last): File "/usr/bin/anaconda/lib/python2.7/site-packages/notebook/base/handlers.py", line 457, in wrapper result = yield gen.maybe_future(method(self, *args, **kwargs)) File "/usr/bin/anaconda/lib/python2.7/site-packages/tornado/gen.py", line 1015, in run value = future.result() File "/usr/bin/anaconda/lib/python2.7/site-packages/tornado/concurrent.py", line 237, in result raise_exc_info(self._exc_info) File "/usr/bin/anaconda/lib/python2.7/site-packages/tornado/gen.py", line 1021, in run yielded = self.gen.throw(*exc_info) File "/usr/bin/anaconda/lib/python2.7/site-packages/notebook/services/contents/handlers.py", line 216, in post yield self._new_untitled(path, type=type, ext=ext) File "/usr/bin/anaconda/lib/python2.7/site-packages/tornado/gen.py", line 1015, in run value = future.result() File "/usr/bin/anaconda/lib/python2.7/site-packages/tornado/concurrent.py", line 237, in result raise_exc_info(self._exc_info) File "/usr/bin/anaconda/lib/python2.7/site-packages/tornado/gen.py", line 285, in wrapper yielded = next(result) File "/usr/bin/anaconda/lib/python2.7/site-packages/notebook/services/contents/handlers.py", line 171, in _new_untitled model = yield gen.maybe_future(self.contents_manager.new_untitled(path=path, type=type, ext=ext)) File "/usr/bin/anaconda/lib/python2.7/site-packages/notebook/services/contents/manager.py", line 338, in new_untitled return self.new(model, path) File "/usr/bin/anaconda/lib/python2.7/site-packages/notebook/services/contents/manager.py", line 364, in new model = self.save(model, path) File "/var/lib/.jupyter/jupyterazure/jupyterazure/httpfscontentsmanager.py", line 84, in save self.create_checkpoint(path) File "/usr/bin/anaconda/lib/python2.7/site-packages/notebook/services/contents/manager.py", line 459, in create_checkpoint return self.checkpoints.create_checkpoint(self, path) File "/usr/bin/anaconda/lib/python2.7/site-packages/notebook/services/contents/checkpoints.py", line 79, in create_checkpoint model = contents_mgr.get(path, content=True) File "/var/lib/.jupyter/jupyterazure/jupyterazure/httpfscontentsmanager.py", line 56, in get 'metadata': {}}) File "/var/lib/.jupyter/jupyterazure/jupyterazure/model.py", line 45, in create_model_from_blob nbformat.version_info[0]) File "/usr/bin/anaconda/lib/python2.7/site-packages/nbformat/__init__.py", line 75, in reads nb = convert(nb, as_version) File "/usr/bin/anaconda/lib/python2.7/site-packages/nbformat/converter.py", line 54, in convert "version doesn't exist" % (to_version)) ValueError: Cannot convert notebook to v5 because that version doesn't exist

此后，主屏幕上会出现一个新的笔记本does，但是如果我尝试打开它，则会收到以下弹出消息：

An unknown error occurred while loading this notebook. This version can load notebook formats v4 or earlier. See the server log for details.

我可以在其他相同的HDI 3.6群集上创建笔记本，但在4.0上则不能。 （我需要4.0，因为我需要使用Spark 2.4。）

以前有没有人经历过/解决过这个问题？

Answer 1

最近，我们在同一问题上看到了几个问题。您可以按照以下步骤解决问题。

解决此问题的步骤：

[Step1：通过ssh连接到头节点并更改文件的内容-/usr/bin/anaconda/lib/python2.7/site-packages/nbformat/_version.py，将5替换为4。

将其更改为：

version_info =（4，0，3）

[Step2：通过Ambari重新启动Jupyter服务。

有关更多详细信息，请参见HDInshight Create not create Jupyter notebook

希望这会有所帮助。如果您还有其他疑问，请告诉我们。

Answer 2

您能告诉我如何通过ssh与headnode连接并按照您提到的那样更改文件的内容...。我被封锁这么久了。谢谢您的帮助@cheektlapradeep
