hive和hadoop仅在本地运行

我已经配置了一个3节点hadoop集群。我试着在上面用Hive。Hive似乎总是只在本地模式下运行。我听说hive从hadoop获取了关于集群的值。所以我在hadoop中运行了一个作业，它似乎也在本地模式下运行。我也在所有三个节点上安装了配置单元。我正在附加日志和配置文件。如果你需要进一步的细节，请问我。

配置单元日志：

INFO  : Number of reduce tasks determined at compile time: 1
INFO  : In order to change the average load for a reducer (in bytes):
INFO  :   set hive.exec.reducers.bytes.per.reducer=<number>
INFO  : In order to limit the maximum number of reducers:

start-dfs.sh和start-yarn.sh启动所有的datanode、namenode、resourcemanager等。集群运行良好，问题似乎只与作业有关。我可以看到所有的数据节点在http://master：50070和http://master:8088
如果您需要任何进一步的日志或配置文件让我知道。谢谢。

问题似乎出在mapred-site.xml上。这是新文件

<configuration>
<property>
    <name>mapreduce.jobhistory.intermediate-done-dir</name>
    <value>/home/huser/hadoop-2.7.1/hadoop_tmp/history/intermediate</value>
</property>
<property>
    <name>mapreduce.jobhistory.done-dir</name>
    <value>/home/huser/hadoop-2.7.1/hadoop_tmp/history/done</value>
</property>
<property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
</property>
<property>
  <name>mapreduce.jobtracker.address</name>
  <value>master:54311</value>
</property>
<property>
  <name>mapreduce.jobtracker.http.address</name>
  <value>master:50030</value>
</property>
</configuration>

这个 mapreduce.job.tracker 似乎不是有效的属性。我也改变了主意 HADOOP_HOME=/home/huser/hadoop-2.7.1/ 至 HADOOP_HOME=/home/huser/hadoop-2.7.1 删除正斜杠 (/) .
我还将hive-site.xml更改为：

<configuration>
    <property>
      <name>javax.jdo.option.ConnectionURL</name>
      <value>jdbc:mysql://master/metastore</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionDriverName</name>
      <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionUserName</name>
      <value>hive</value>
    </property>
    <property>
      <name>javax.jdo.option.ConnectionPassword</name>
      <value>1</value>
    </property>
    <property>
      <name>datanucleus.autoCreateSchema</name>
      <value>false</value>
    </property>
    <property>
      <name>datanucleus.fixedDatastore</name>
      <value>true</value>
    </property>
    <property>
      <name>hive.metastore.uris</name>

    </property>
</configuration>
