[ISSUE] Single node cluster not working in version 0.3.2

[JCZuurmond]

Hi there,

With version 0.3.2 a single node cluster fails to be created:

Error: NumWorkers could be 0 only for SingleNode clusters. See https://docs.databricks.com/clusters/single-node.html for more details

When fixing the version to 0.3.1 the apply does not fail.

Affected Resource(s)

• databricks_cluster

Terraform Configuration Files

resource "databricks_cluster" "single_node" {
  cluster_name                    = "single-node"
  spark_version                   = data.databricks_spark_version.latest.id
  node_type_id                   = data.databricks_node_type.smallest.id
  autotermination_minutes = 10
  num_workers                    = 0

  spark_conf = {
    "spark.master": "local[*]",
    "spark.databricks.cluster.profile": "singleNode"
  }
}

My hunch is that it has something to do with PR #571. Maybe @alexott could help us here.

I think you're missing custom_tags. Please check documentation
