私はhadoop 2.5.2を使用しています。私はhadoopとmap reduceを初めて使用しています。感情分析を行うためにmap reduceコードを試してみました。しかし、私がコードを実行すると、コンソール上にhadoopによってたくさんのログメッセージが生成されます。それぞれの文の解析結果を与えるのに時間がかかる理由があります。私は同様の質問を参照しているコンソールでhadoopによって生成されたログメッセージを抑制する方法

ロギングメッセージは....すでにstackoverflowの[how to suppress Hadoop logging message on the consoleに尋ねたが、それはhasnt私を助けてくれniether明確な答えが議論されています。私は、次のいくつかのフォーラムで提案した構成が、そのないworking.Iを使用してみました
..私はまた、次の値を設定することで、log4j.propertiesファイルを編集しようとしているhadoop-env.shexport HADOOP_HOME_WARN_SUPPRESS=1
export HADOOP_ROOT_LOGGER="WARN,DRFA"
で次の設定を試してみました
hadoop.root.logger=WARN,DRFA
hadoop.log.dir=.
hadoop.log.file=hadoop.log
しかし、私は実行時の実行中にhadoop mapreduceによって生成されたこのログメッセージを取り除くことができません。コンソール上で私の出力も遅れています。それらの回避策やjavaコードを私に埋め込むことができます。コードとメッセージを抑制してください。何か提案、助け...誰も知っている??
ありがとうございます！
