Запуск Hadoop Wordcount Ошибка работы

Question

Я новичок в использовании Hadoop, и в настоящее время я пытаюсь запустить wordcount на кластере с одним узлом на рабочем столе ubuntu. Я пытаюсь следовать этому руководству, чтобы выполнить задание Hadoop:

http://javabeginnerstutorial.com/hadoop/your-first-hadoop-map-reduce-job/

В настоящее время я застрял на шаге 3, когда я пытаюсь mvn clean install, это ошибка я получаю. Я использую тот же самый файл pom.xml, который связан на шаге 3. Должен ли я что-то редактировать в файле pom.xml, чтобы успешно скомпилировать? Или ссылки, возможно, не сработают? Любая помощь будет большой. Благодарю.

Answer 1

Try, чтобы получить POM и Maven dependice от этого http://mvnrepository.com/artifact/org.apache.hadoop/hadoop-mapreduce-client-core Try, чтобы проверить версию Hadoop, прежде чем добавить этот файл POM.

Answer 2

Выполните команду Maven с -DskipTests
