我正在使用hadoop 2.5.2.I我是hadoop和map reduce的新手。我尝试使用map reduce代码来执行情感分析。但是当我执行代码时，很多日志消息是由控制台上的hadoop生成的。这就是为每个句子给出分析结果花费大量时间的原因。以下是该日志消息....如何在控制台上抑制由hadoop生成的日志消息

我也提到了类似的问题已经问在计算器[how to suppress Hadoop logging message on the console但它未帮助我niether明确的答案进行了讨论。我试着用在一些论坛上建议如下配置，但在hadoop-env.sh
export HADOOP_HOME_WARN_SUPPRESS=1
export HADOOP_ROOT_LOGGER="WARN,DRFA"
下它不是working.I试图设置我也试图通过设置以下值编辑log4j.properties文件..
hadoop.root.logger=WARN,DRFA
hadoop.log.dir=.
hadoop.log.file=hadoop.log
但是还是我不能够摆脱延迟控制台上我的输出中运行execution.Its用的Hadoop MapReduce的生成此日志消息作为well.Is他们的任何解决办法或任何Java代码，我可以在我的嵌入代码和压制messages.any建议，帮助..任何人都知道？
非常感谢！
