When creating a Google Cloud Dataproc cluster, you can specify initialization actions in executables and/or scripts that Cloud Dataproc will run on all nodes in your Cloud Dataproc cluster immediately after the cluster is set up.
Initialization actions are stored in a Google Cloud Storage bucket and can be passed as a parameter to the gcloud command or the clusters.create API when creating a Cloud Dataproc cluster. For example, to specify an initialization action when creating a cluster with the gcloud command, you can run:
gcloud dataproc clusters create CLUSTER-NAME
[--initialization-actions [GCS_URI,...]]
[--initialization-action-timeout TIMEOUT]
For convenience, copies of initialization actions in this repository are stored in the following Cloud Storage bucket, which is publicly accessible:
gs://dataproc-initialization-actions
The folder structure of this Cloud Storage bucket mirrors this repository. You should be able to use this Cloud Storage bucket (and the initialization scripts within it) for your clusters.
These samples are provided to show how various packages and components can be installed on Cloud Dataproc clusters. You should understand how these samples work before running them on your clusters. The initialization actions provided in this repository are provided without support and you use them at your own risk.
This repository presently offers the following actions for use with Cloud Dataproc clusters.
- Install packages/software on the cluster:
- Configure the cluster:
- Configure a nice shell environment
- Share a NFS consistency cache
- Share a Google Cloud SQL Hive Metastore
- Setup Google Stackdriver monitoring for a cluster
Single Node clusters have dataproc-role set to Master and dataproc-worker-count set to 0. Most of the initialization actions in this repository should work out of the box, as they run only on the master. Examples include notebooks (such as Apache Zeppelin) and libraries (such as Apache Tez). Actions that run on all nodes of the cluster (such as cloud-sql-proxy) similarly work out of the box.
Some initialization actions are known not to work on Single Node clusters. All of these expect to have daemons on multiple nodes.
- Apache Drill
- Apache Flink
- Apache Kafka
- Presto
- Apache Zookeeper
Feel free to send pull requests or file issues if you have a good use case for running one of these actions on a Single Node cluster.
