Question: 1 / 400

What error message indicates that Hadoop is not found when running spark-shell?

No class definition found error

The correct indication that Hadoop is not found when running spark-shell is encapsulated in the message that explicitly states a failure to initialize or establish a Hadoop context. This message typically arises when the Spark session attempts to interface with Hadoop components but is unable to do so due to missing configurations or library dependencies.

In the context of this question, the message "Failed to initialize Hadoop context" directly highlights the inability to locate necessary Hadoop libraries or configurations, indicating a fundamental issue with Hadoop's integration within the Spark environment. While other options may pertain to general errors in Java execution or missing classes, they do not specifically suggest the absence of Hadoop, making them less relevant to this situation.
