无法初始化集群.请检查您的配置是否包含mapreduce.framework.name和相应的服务器地址

问题描述

我试图通过将所有必需的jar添加到来自Java命令行路径(./java -cp的类路径中来运行相同的代码(org.apache.hadoop.hbase.mapreduce.Export)导出类. :/npachava/*导出测试/test)，出现以下错误.

I am trying to run the same code(org.apache.hadoop.hbase.mapreduce.Export) Export class by adding the all the required jars to the class path from java command line path( ./java -cp ".:/npachava/*" Export test /test) ,I am getting following error.

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.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导出测试/TestTableData)的命令提示符下运行即可.

But running from the command prompt fromthe hbase bin directory( ./hbase org.apache.hadoop.hbase.mapreduce.Driver export test /TestTableData) works perfectly fine.

我尝试将配置设置为yarn/local，但是都没有起作用

I have tried to set the config to yarn/local but both didnt worked

Configuration conf = HBaseConfiguration.create();
conf.set("mapreduce.framework.name", "yarn"); also with "local"

任何人都可以帮助

我在Linux上使用hbase 0.94.17版本运行.

I am running with hbase 0.94.17 version on my linux.

推荐答案

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

add hadoop-mapreduce-client-jobclient.jar (select hadoop version before downloading).
