①maven压缩包
②Eclipse压缩包
③本地仓库压缩包
11、创建maven项目工程alimaven central aliyun maven http://maven.aliyun.com/nexus/content/repositories/central/
12、修改完后右键工程项目更新工程4.0.0 bigdata-hadoop bigdata-mapreduce0.0.1-SNAPSHOT bigdata-mapreduce http://www.example.com aliyun http://maven.aliyun.com/nexus/content/groups/public/ cloudera https://repository.cloudera.com/artifactory/cloudera-repos/ jboss http://repository.jboss.org/nexus/content/groups/public UTF-8 1.7 1.7 2.6.0-cdh5.14.2 org.apache.hadoop hadoop-common2.6.0-cdh5.14.2 org.apache.hadoop hadoop-client2.6.0-cdh5.14.2 org.apache.hadoop hadoop-hdfs2.6.0-cdh5.14.2 junit junit4.11 test jdk.tools jdk.tools1.8 system ${JAVA_HOME}/lib/tools.jar
可以多次更新update,多试几次,直到项目没有红色大叉为止
