私は micheal install ( http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/ ) に従いました。

コマンド /usr/local/hadoop/bin/start-all.sh を実行すると、通常、マシン上で Namenode、Datanode、Jobtracker、および Tasktracker が起動します。

ここで開始されたTaskTrackerのみがトレースです：

hduser@srv591 ~ $ /usr/local/hadoop/bin/start-all.sh
starting namenode, logging to /usr/local/hadoop/libexec/../logs/hadoop-hduser-namenode-srv591.out

hduser@srv591 ~ $ /usr/local/java/bin/jps
19469 TaskTracker
19544 Jps

Tariqの解決策は機能しますが、それでもjobtrackerとnamenodeを開始するには、ここでログの内容です

ディレクトリ/app/hadoop/tmp/dfs/namesecondaryを作成し、適切な権限を持っていることを確認してください。また、ログ (NN、DN、SNN、JT) を調べると役立ちます。問題が解決しない場合は、ログと構成ファイルを提示してください。

あなたのコメントに応えて：

org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: ディレクトリ /app/hadoop/tmp/dfs/name が矛盾した状態です: ストレージ ディレクトリが存在しないか、アクセスできません。

構成ファイルで使用しているディレクトリを作成していないようです。この例外はそれを明確に示しています。構成プロパティの値として使用している適切な権限を持つすべてのディレクトリを作成したことを確認してください。

デフォルトの Hadoop インストールでは、datanode および namenode データ ディレクトリをローカル ディスク上の /tmp ディレクトリとして使用します。正しい方法は、ローカルに datanode と namenode のデータ ディレクトリを手動で作成し、パスを hdfs-site.xml に入れることです。次のプロパティを /etc/hadoop/hdfs-site.xml に追加し、名前ノードを再フォーマットして再起動すると修正されるはずです。

<property>
 <name>dfs.namenode.name.dir</name>
 <value>file:///data/1/dfs/nn,file:///data/2/dfs/nn</value>
</property>
<property>
 <name>dfs.datanode.data.dir</name>
