попробуйте исправить конфликт в отношении commons-cli:1.3.1 с 1.2:
выберите 1.3.1, затем ошибка 1;
выберите 1.2, затем ошибка 2;
добавьте раздел общего доступа зависимостей 1.4, затем ошибка 1.

 1、commons-cli choose 1.3.1 or 1.4
2、add $hadoop_home/../hadoop_mapreduce/* to yarn.application.classpath
