为什么我不能创建同时安装了 Jupyter 和 DataLab 的 Google DataProc 集群？
Why can't I create a Google DataProc cluster with both Jupyter and DataLab installed?
我想在安装了 Jupyter 和 DataLab 的 DataProc 中创建一个集群（我知道它们非常相似，但团队成员有不同的偏好）。我可以用它们中的任何一个创建集群：
使用 Jupyter 的集群：
gcloud dataproc clusters create $DATAPROC_CLUSTER_NAME_JUPYTER \
--project $PROJECT \
--bucket $BUCKET \
--zone $ZONE \
--initialization-actions gs://dataproc-initialization-actions/connectors/connectors.sh,gs://dataproc-initialization-actions/jupyter/jupyter.sh \
--metadata gcs-connector-version=$GCS_CONNECTOR_VERSION \
--metadata bigquery-connector-version=$BQ_CONNECTOR_VERSION \
--metadata JUPYTER_PORT=$JUPYTER_PORT,JUPYTER_CONDA_PACKAGES=numpy:scipy:pandas:scikit-learn
DataLab 集群：
gcloud dataproc clusters create $DATAPROC_CLUSTER_NAME_DATALAB \
--project $PROJECT \
--bucket $BUCKET \
--zone $ZONE \
--master-boot-disk-size $MASTER_DISK_SIZE \
--worker-boot-disk-size $WORKER_DISK_SIZE \
--initialization-actions gs://dataproc-initialization-actions/connectors/connectors.sh,gs://dataproc-initialization-actions/datalab/datalab.sh \
--metadata gcs-connector-version=$GCS_CONNECTOR_VERSION \
--metadata bigquery-connector-version=$BQ_CONNECTOR_VERSION \
--scopes cloud-platform,bigquery
两者都很好用。但是，当我尝试用它们创建一个集群时，它失败了：
gcloud dataproc clusters create test \
--project $PROJECT \
--bucket $BUCKET \
--zone $ZONE \
--initialization-actions gs://dataproc-initialization-actions/connectors/connectors.sh,gs://dataproc-initialization-actions/datalab/datalab.sh,gs://dataproc-initialization-actions/jupyter/jupyter.sh \
--metadata gcs-connector-version=$GCS_CONNECTOR_VERSION \
--metadata bigquery-connector-version=$BQ_CONNECTOR_VERSION \
--metadata JUPYTER_PORT=$JUPYTER_PORT,JUPYTER_CONDA_PACKAGES=numpy:scipy:pandas:scikit-learn \
--scopes cloud-platform,bigquery
错误信息是：

看起来有一个克隆步骤阻止了安装成功。我该如何解决这个问题？任何建议表示赞赏，谢谢。
这似乎是 init 操作中的错误，我们无法 git clone 存储库两次。我们会解决这个问题。
同时，您可以尝试 Jupyter optional component 使用数据实验室初始化操作。
