Show answer & explanation
Correct answer: C
Answer: Both statements are true.
Statement (i): Facebook has operated one of the world's largest Hadoop clusters for storing and processing its large-scale data. Many industry reports and case studies cite Facebook's Hadoop deployment as among the largest in scale.
Statement (ii): Hadoop 2.0 introduced YARN (Yet Another Resource Negotiator), a general resource-management layer that allows multiple processing frameworks to run on the same cluster. This enables stream-processing frameworks (for example, Apache Storm or Spark Streaming) to perform live/real-time data processing alongside batch jobs.
Therefore, both statements are true.
