Hadoop 2.2.0配置弃用 [英] Hadoop 2.2.0 Configuration deprecation

问题描述

我建立了Hadoop 2.2.0集群，现在运行我的Java客户端来处理数据。运行我的java程序后，我注意到输出显示如下：

I set up the Hadoop 2.2.0 Cluster and now running my java client to process data. After running my java program, I notice the output displays like this:

13/11/18 11:44:44 INFO Configuration.deprecation: user.name is deprecated. Instead, use mapreduce.job.user.name
13/11/18 11:44:44 INFO Configuration.deprecation: mapred.jar is deprecated. Instead, use mapreduce.job.jar

13/11/18 11:44:44 INFO Configuration.deprecation: mapred.working.dir is deprecated. Instead, use mapreduce.job.working.dir

模块运行良好，看起来像没有'不影响任何东西。但是，我怎样才能避免这些信息？ （我导入maven hadoop-client 2.2.0并使用Job job = new Job（））

The module is working well and looks like that doesn't affect anything. But how can I avoid this info messages? (I import maven hadoop-client 2.2.0 and use Job job = new Job())

推荐答案

它在Hadoop 2.3中得到了修复，请参阅： https://issues.apache.org/jira/browse/HADOOP-10178

It's fixed in Hadoop 2.3, please refer: https://issues.apache.org/jira/browse/HADOOP-10178
