Dataproc: Qwik Start

Dataproc: Qwik Start

Dataproc is a fast, easy-to-use, fully-managed cloud service for running Apache Spark and Apache Hadoop clusters in a simpler, more cost-efficient way. Operations that used to take hours or days take seconds or minutes instead. Create Dataproc clusters quickly and resize them at any time, so you don’t have to worry about your data pipelines outgrowing your clusters.

• Create a Dataproc cluster using the command line
• Run a simple Apache Spark job
• Modify the number of workers in the cluster

Create a cluster

Dataproc creates staging and temp buckets that are shared among clusters in the same region. Since we’re not specifying an account for Dataproc to use, it will use the Compute Engine default service account, which doesn’t have storage bucket permissions by default.

The command specifies:

• That you want to run a spark job on the example-cluster cluster
• The class containing the main method for the job’s pi-calculating application
• The location of the jar file containing your job’s code
• The parameters you want to pass to the job—in this case, the number of tasks, which is 1000
