我试图通过从java命令行路径(./java -cp“.：/ npachava”添加所有必需的jar到类路径来运行相同的代码(org.apache.hadoop.hbase.mapreduce.Export)导出类/ *“导出测试/测试”,我收到以下错误.
Exception in thread "main" java.io.IOException: Cannot initialize Cluster. Please check your configuration for mapreduce.framework.name and the correspond server addresses.

但是从hbase bin目录(./hbase org.apache.hadoop.hbase.mapreduce.Driver export test / TestTableData)的命令提示符运行完全正常.
我试图将配置设置为yarn / local但两者都没有用
Configuration conf = HBaseConfiguration.create();
conf.set("mapreduce.framework.name", "yarn"); also with "local"
有人请帮忙
我在我的linux上运行hbase 0.94.17版本.
解决方法:
添加hadoop-mapreduce-client-jobclient.jar(下载前选择hadoop版本).
