Terraformの "aws_emr_cluster" でbootstrap_actionを複数指定する

こんな感じで並べればOKでした。

resource "aws_emr_cluster" "emr-cluster" {
  name          = "emr-cluster"
  release_label = "emr-5.3.0"
  applications  = ["Spark"]

  ## 省略

  bootstrap_action {
    path = "s3://elasticmapreduce/bootstrap-actions/run-if"
    name = "runif"
    args = ["instance.isMaster=true", "echo running on master node"]
  }
  bootstrap_action {
    path = "s3://elasticmapreduce/bootstrap-actions/run-if"
    name = "runif"
    args = ["instance.isMaster=false", "echo running on core node"]
  }
