Question

我试图在我的单集群设置中运行Pig或Hive中的HelloWorld编程。我的所有应用程序都挂了。这包括我在猪身上的字数。我的Hive命令也挂起：

SELECT COUNT(*) FROM u_data;

My Hive logs stops as follows: set mapreduce.job.reduces=<number>
Starting Job = job_1433035285759_0006, Tracking URL = http://der-Inspiron-3521:8088/proxy/application_1433035285759_0006/
Kill Command = /home/der/utility/hadoop-2.7.0/bin/hadoop job  -kill job_1433035285759_0006

我按照链接。该应用程序显示

status = undefined

这是我的map-reduce配置文件：

<configuration>
  <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
<property>
<property>
  <name>mapreduce.jobhistory.address</name>
  <value>localhost:10020</value>
  <description>Host and port for Job History Server (default 0.0.0.0:10020)</description>
</property>

  <name>mapreduce.jobtracker.http.address</name>
  <value>localhost:50030</value>
  <description>The host and port that the MapReduce job tracker runs
  at.  If "local", then jobs are run in-process as a single map
  and reduce task.
  </description>
</property>

</configuration>

我的hadoop服务器是2.7.0版。我试过hadoop服务器2.6.0，但我还有其他问题。

我的猪脚本在MapReduce启动阶段挂起：

    mapReduceLayer.MapReduceLauncher -
