Explanation
In a FusionInsight (Huawei's enterprise Hadoop distribution) cluster, Spark interacts with all four components: Hive (A) for SQL-based queries via Spark SQL and the HiveContext, which reads Hive metastore tables; YARN (B) as the resource manager that schedules and allocates containers for Spark executors and drivers; HDFS (C) as the primary distributed storage layer where Spark reads input data and writes output; and ZooKeeper (D) for high-availability coordination, such as leader election for Spark History Server and cluster state management. Since every option is correct, there are no distractors to eliminate - all four are genuine, first-class integration points in the FusionInsight ecosystem.
Memory tip: Think of the acronym YHZH (YARN, HDFS, ZooKeeper, Hive) - or simply remember that Spark is a compute engine only, so it depends on external systems for resources (YARN), storage (HDFS), coordination (ZooKeeper), and metadata/SQL (Hive). Any question asking what Spark "mainly interacts with" in a Hadoop cluster is testing whether you know Spark doesn't do these things itself.
