What is the name of the machine learning library used in Apache Spark?

Detailed Answer in Step-by-Step Solution:

Objective: Identify Apache Spark’s ML library.

Understand Spark: A big data framework with specialized libraries.

Evaluate Options:

A: MLib (correctly MLlib)—Spark’s machine learning library.

B: GraphX—Graph processing, not ML.

C: Structured Streaming—Streaming data, not ML.

D: HadoopML—Not a Spark library (Hadoop-related).

Reasoning: MLlib is Spark’s official ML toolkit (e.g., regression, clustering).

Conclusion: A is correct (noting “MLib” should be “MLlib”).

OCI Data Science supports Spark via Data Flow, where “MLlib (Machine Learning library) provides scalable ML algorithms.” GraphX (B) and Structured Streaming (C) serve other purposes, and HadoopML (D) isn’t real—MLlib (A) is the standard, despite the typo.
