我正在使用hadoop 2.5.2.I我是hadoop和map reduce的新手。我嘗試使用map reduce代碼來執行情感分析。但是當我執行代碼時，很多日誌消息是由控制檯上的hadoop生成的。這就是爲每個句子給出分析結果花費大量時間的原因。以下是該日誌消息....如何在控制檯上抑制由hadoop生成的日誌消息

我也提到了類似的問題已經問在計算器[how to suppress Hadoop logging message on the console但它未幫助我niether明確的答案進行了討論。我試着用在一些論壇上建議如下配置，但在hadoop-env.sh
export HADOOP_HOME_WARN_SUPPRESS=1
export HADOOP_ROOT_LOGGER="WARN,DRFA"
下它不是working.I試圖設置我也試圖通過設置以下值編輯log4j.properties文件..
hadoop.root.logger=WARN,DRFA
hadoop.log.dir=.
hadoop.log.file=hadoop.log
但是還是我不能夠擺脫延遲控制檯上我的輸出中運行execution.Its用的Hadoop MapReduce的生成此日誌消息作爲well.Is他們的任何解決辦法或任何Java代碼，我可以在我的嵌入代碼和壓制messages.any建議，幫助..任何人都知道？
非常感謝！
