格式化hdfs后，出现以下错误：

************************************************************/

以下是我所做的步骤：

sbin/stop-dfs.sh
 hdfs namenode -format
 sbin/start-dfs.sh

供您参考：我的 core-site.xml文件 有体温吗 目录 具体如下：

<property>
      <name>hadoop.tmp.dir</name>
     <value>/usr/local/hadoop</value>
      <description>A base for other temporary directories.    
</description>
 </property>

还有我的 hdfs-site.xml文件 作为 名称节点 和 数据节点 具体如下：

<property>
     <name>dfs.namenode.name.dir</name>  
     <value>file:/usr/local/hadoop/dfs/namenode</value>
  </property>
 <property> 
        <name>dfs.datanode.data.dir</name>
        <value>file:/usr/local/hadoop/dfs/datanode</value>
    </property>

更新：我有一点进一步的问题，但我仍然得到相同类型的错误。我有能力运行 hdfs dfs -format 并按建议更改版本**。之后我用 hdfs dfs -ls and hdfs dfs -mkdir to create /user/der 我的登录名是什么。但是，当我运行mypig文件时，我在pig文件中获取mkdirs和chmod错误。以下是my datanode和namenode的权限：

drwx------ 3 der  der  4096 May 29 08:13 datanode
drwxrwxrwx 4 root root 4096 May 28 11:34 name
drwxrwxr-x 3 der  der  4096 May 29 08:13 namenode
drwxrwxr-x 3 der  der  4096 May 29 08:13 namesecondary
drwxr-xr-x 2 root root 4096 May 28 11:46 ww

似乎datanode只有所有者和组的权限，而没有用户的权限。
以下是我的pig脚本错误：

这是我的Pig剧本：

records = LOAD '1987.csv' USING PigStorage(',') AS
        (Year, Month, DayofMonth, DayOfWeek, 
         DepTime, CRSDepTime, ArrTime, CRSArrTime, 
         UniqueCarrier, FlightNum, TailNum,ActualElapsedTime,
         CRSElapsedTime,AirTime,ArrDelay, DepDelay, 
         Origin, Dest,  Distance:int, TaxIn, 
         TaxiOut, Cancelled,CancellationCode,  Diverted, 
         CarrierDelay, WeatherDelay, NASDelay, SecurityDelay,
         lateAircraftDelay);
milage_recs= GROUP records ALL;
tot_miles = FOREACH milage_recs GENERATE SUM(records.Distance);
STORE tot_miles INTO 'totalmiles4';

更新：顺便说一下，我在datanode上使用了chmodgo+rw（在我停止namenode服务器和datanode服务器之后）。但效果不太好。
更新5月30日：多一点细节。我将pig脚本中pig脚本的父目录更改为：

records = LOAD '/user/der/1987.csv' USING PigStorage(',') AS

我也有同样的错误。在客户端，这里是错误。唯一的区别是，失败的输入读取没有hdfs://前缀。

Failed to read data from "/user/der/1987.csv"
Output(s):
Failed to produce result in "hdfs://localhost:9000/user/der/totalmiles4"

在服务器端，这里是namenode日志，就在我从pig脚本得到无效文件请求的那一刻。日志（使用tail-f）滚动。这表示服务器正在接受pig命令的请求。

我只需要获取pig脚本的源代码并检查它发出的extact hdfs命令。我认为我配置的hadoop hdfs服务有问题。
