无法初始化群集.请检查mapreduce.framework.name的配置和相应的服务器地址

Question

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.
    at org.apache.hadoop.mapreduce.Cluster.initialize(Cluster.java:120)
    at org.apache.hadoop.mapreduce.Cluster.<init>(Cluster.java:82)

    at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:1308)
    at Export.main(Export.java:194)

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.

Answer 1

添加hadoop-mapreduce-client-jobclient.jar(下载前选择hadoop版本).

Answer 2

解决@mentya说.

如果您使用的是Maven,您也可以将它添加到您的pom.xml中.

    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-mapreduce-client-jobclient</artifactId>
        <version>${hadoop.version}</version>
        <scope>provided</scope>
    </dependency>
