In this scenario, you create a Spark Batch Job to write data about some movie directors into the MongoDB default database and then read the data from this database.

This data contains the names of these directors and the ID numbers distributed to them.
Note that the sample data is created for demonstration purposes only.
tHDFSConfiguration is used in this scenario by Spark to connect to the HDFS system where the jar files dependent on the Job are transferred.
Yarn mode (Yarn client or Yarn cluster):
When using Google Dataproc, specify a bucket in the Google Storage staging bucket field in the Spark configuration tab.
When using HDInsight, specify the blob to be used for Job deployment in the Windows Azure Storage configuration area in the Spark configuration tab.
- When using Altus, specify the S3 bucket or the Azure Data Lake Storage for Job deployment in the Spark configuration tab.
- When using Qubole, add a tS3Configuration to your Job to write your actual business data in the S3 system with Qubole. Without tS3Configuration, this business data is written in the Qubole HDFS system and destroyed once you shut down your cluster.
When using on-premise distributions, use the configuration component corresponding to the file system your cluster is using. Typically, this system is HDFS and so use bix1550477842760.html.
If you are using Databricks without any configuration component present in your Job, your business data is written directly in DBFS (Databricks Filesystem).
Prerequisite: ensure that the Spark cluster and the MongoDB database to be used have been properly installed and are running.
To replicate this scenario, proceed as follows:
