我可以将 GCP Dataproc 集群从标准（1 个主节点，N 个工作节点）更改为高可用性吗？

Question

I have created a GCP Dataproc cluster with Standard (1 master, N workers). Now I want to upgrade it to High Availability (3 masters, N workers) - Is it possible?

I tried GCP, GCP alpha and GCP beta commands. For example GCP beta documented here: https://cloud.google.com/sdk/gcloud/reference/beta/dataproc/clusters/update .

It has option to scale worker nodes, however does not have option to switch from standard to high availability mode. Am I correct?

Answer 1

您可以通过进入集群下的虚拟机实例部分来升级主节点，停止主虚拟机并编辑配置以

Answer 2

The answer is - no. Once HA cluster is created, it can't be downgraded and vice versa. You can add worker nodes, however master node can't be altered.

Answer 3

You may always upgrade your master node machine type and also add more worker node. While that would improve your cluster job performance but noting to do with HA.

Answer 4

是的，你总是可以这样做的，要改变master节点的机器类型，你首先需要停止master虚拟机实例，然后你可以改变机器类型即使worker节点的机器类型可以改变，我们只需要做的是停止机器并编辑机器配置。
