hadoop - Windows 7にHadoopをインストールすると、hadoop namenode –formatの実行に失敗します

Question

このブログを使用して、Hadoopを初めてWindows7にインストールします：http： //blog.sqltrainer.com/2012/01/installing-and-configuring-apache.html

1. パッケージopensshをサービスとしてインストールしたCygwin
2. ダウンロードして解凍したhadoop-1.0.4

3. 次に、JAVA_HOMEを構成してチェックしました。

   $ bin/hadoopバージョン

   Hadoop 1.0.4 
   Subversion svn.apache.org/repos/asf/hadoop/common/branches/branch-1.0 -r 1393290 
   Compiled by hortonfo on Wed Oct  3 05:13:58 UTC 2012 
   From source with checksum fe2baea87c4c81a2c505767f3f9b71f4
   

4. hdfs-site.xmlコンテンツ：

   <configuration>
   <property>
       <name>fs.default.name</name>
       <value>hdfs://localhost:47110</value>
   </property>
   <property>
       <name>mapred.job.tracker</name>
       <value>localhost:47111</value>
   </property>
   <property>
       <name>dfs.replication</name>
       <value>2</value>
   </property>
   </configuration>
   

5. mapred-site.xmlコンテンツ：

   <configuration>
   <property>
       <name>mapred.job.tracker</name>
       <value>localhost:8021</value>
   </property>
   </configuration>
   

6. ディスクスペースをフォーマットしようとすると、次のようになります。

   $ ./bin/hadoop namenode –format

   13/02/12 10:16:34 INFO namenode.NameNode: 
   STARTUP_MSG: /************************************************************

7. 始めようとすると、次のようになります。

   $ bin / start-dfs.sh

hadoop namenode –formatネットで例外を検索すると、セクション6で行ったように、実行するための答えが得られます。

助けてください。

私は問題を解決しました：私はコマンドをコピーしました：hadoop namenode –formatインターネットページから。キーボードで文字「-」を書くだけでうまくいきました。
