In FusionInsight HD, use the Streaming command line to submit the om.huawei.examole.WordCount task in example.jar. The task name is wcTest. Which of the following commands is correct?

Question

Options

• Astorm jar example .jar wcTest om.huawei.example.WordCount
• Bstorm jar example .jar wcTest WordCount
• Cstorm jar example .jar om.huawei.example.WordCount wcTest
• Dstorm jar example.jar WordCount wcTest

• A
  5% (1)
• B
  5% (1)
• C
  81% (17)
• D
  10% (2)

Explanation

Option C follows the correct Apache Storm CLI syntax: storm jar <jar_file> <main_class> <topology_name>, placing the JAR first, then the fully-qualified class name, then the topology name - matching all three requirements in the question (file: example.jar, class: om.huawei.example.WordCount, task name: wcTest).

Why the distractors fail:

• A swaps the class name and topology name (wcTest appears before the class), and introduces a space in example .jar
• B swaps the order and drops the package prefix, using only WordCount instead of the full om.huawei.example.WordCount
• D uses the correct order but omits the package path, making the class name unresolvable

Memory tip: Think of it as "Jar, Class, Name" - JCN order: the JAR file comes first, the fully-qualified Class comes second, and the topology Name comes last. Any command that puts the name before the class, or drops the package prefix, is wrong.
