jupyter-notebook - 为什么我无法创建同时安装了 Jupyter 和 DataLab 的 Google DataProc 集群？

问题描述

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）。我可以使用其中任何一个创建集群：

与 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

使用 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

两者都运作良好。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：

ERROR: (gcloud.dataproc.clusters.create) Operation [projects/abc/regions/global/operations/d34943dc-5bda-386f-af91-db6e0516e2c5] failed: Multiple Errors:

test-m 中的文件如下所示：

++ /usr/share/google/get_metadata_value attributes/dataproc-role
+ readonly ROLE=Worker
+ ROLE=Worker
++ /usr/share/google/get_metadata_value attributes/INIT_ACTIONS_REPO

+ git clone -b master --single-branch https://github.com/GoogleCloudPlatform/dataproc-initialization-actions.git
fatal: destination path 'dataproc-initialization-actions' already exists and is not an empty directory.

看起来有一个克隆步骤会阻止安装成功。我该如何解决这个问题？任何建议表示赞赏，谢谢。

解决方案

这似乎是 init 操作中的一个错误，我们无法git clone两次存储存储库。我们会解决这个问题。

同时，您可以尝试使用 Jupyter 可选组件来代替 datalab init 操作。
