A financial services company needs to process a continuous stream of stock market ticks, detect anomalies in real time, and also run historical analysis on the same data. They want to use a single processing framework to minimize operational complexity. Which approach is most appropriate?

Use HDFS for ingestion and Hive for real-time processing

Use Kafka for ingestion and Spark Streaming for real-time processing, with the same data also available for batch analysis in Spark

Use Sqoop for ingestion and Pig for real-time processing

Use Flume for ingestion and MapReduce for real-time processing

What is the primary use case for Apache Pig?

Scripting data flows and ETL processes

SQL-like querying and data warehousing

Real-time random read/write access to large tables

Streaming data ingestion and messaging

What is the primary purpose of HDFS in a Hadoop cluster?

To execute MapReduce jobs in parallel

To provide a SQL-like interface for querying data

To provide a distributed file system for storing large datasets across multiple nodes

To manage cluster resources and schedule tasks
