A new workload has been deployed to Cloud Dataproc, configured with an autoscaling policy. Intermittently, a FetchFailedException is observed. What is the most probable cause of this issue?
A
The autoscaling policy is scaling down too quickly, leading to loss of shuffle data when a node is decommissioned.
B
The GCS bucket in use has incorrect access controls configured.
C
The autoscaling policy is adding nodes at a rapid pace, causing data to be dropped.
D
Google Cloud Storage is being utilized for persistent storage instead of local storage.
