The program that has been developed Hadoop2.2.0 with Maven before. Environment changed to CDH5.2 after the error, found that Maven relies on the library problem. have been using http://mvnrepository.com/to find Maven dependencies before. But such sites can only find generic maven dependencies, not including CDH dependencies. Fortunately Cloudera provides a CDH dependency:Http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cdh_vd_cdh5_maven_repo.htmlIn short, add the foll

files! I tried to copy a patch pom file to Windows, and then compile the mahout0.9 source code in the Windows environment, but it doesn't work, all kinds of errors. Since Mahout-core relies on only two mahout-related jar packages,Mahout-core-0.9.jar and Mahout-math-0.9.jar , so we only need to overwrite the two jar packages that support Hadoop2.2.0 on the cluster locally. If you do not perform this step, the project will report a Hadoop compatibility exception when the jar is copied to the clus
