Google Data Engineer Sample Questions:
You want to migrate an on-premises Hadoop system to Cloud Dataproc. Hive is the primary tool in use, and the data format is Optimized Row Columnar (ORC). All ORC files have been successfully copied to a Cloud Storage bucket. You need to replicate some data to the cluster's local Hadoop Distributed File System (HDFS) to maximize performance. What are two ways to start using Hive in Cloud Dataproc? (Choose two.)
- A. Mount the Hive tables from HDFS.
- B. Replicate external Hive tables to the native ones.
- C. Mount the Hive tables locally.
- D. Replicate external Hive tables to the native ones.
- E. Run the gsutil utility to transfer all ORC files from the Cloud Storage bucket to the master node of the Dataproc cluste
- F. Run the gsutil utility to transfer all ORC files from the Cloud Storage bucket to HDF
- G. Run the gsutil utility to transfer all ORC files from the Cloud Storage bucket to any node of the Dataproc cluste
- H. Leverage Cloud Storage connector for Hadoop to mount the ORC files as external Hive table
- I. Load the ORC files into BigQuer
- J. Mount the Hive tables locally.
- K. Leverage BigQuery connector for Hadoop to mount the BigQuery tables as external Hive table
- L. Then run the Hadoop utility to copy them do HDF
