私はマックを使用しています。以下のコマンドを実行すると、例外がスローされます。Hadoop の例の jar を試してみましたが、同じ例外がスローされます。
「jps」は次の出力を提供します。
5103 NameNode
5613 Jps
5343 JobTracker
5277 SecondaryNameNode
5430 TaskTracker
したがって、私の JobTracker は既に実行されているはずです。
私が実行すると：
bin/hadoop jar hadoop-cookbook-chapter1.jar chapter1.WordCount input output
次の例外が発生します。
