hadoop - Hive和Hadoop仅在本地运行

转载作者：行者123 更新时间：2023-12-02 21:28:40

我已经配置了一个3节点Hadoop集群。我试图在其上使用Hive。 Hive似乎总是只在本地模式下运行。我听说Hive从Hadoop获得了有关集群的值(value)。因此，我在Hadoop中进行了一项工作，它似乎也在本地模式下运行。我也在所有三个节点上都安装了Hive，并附加了日志和配置文件。请问我是否需要其他详细信息。

hive 日志:

INFO  : Number of reduce tasks determined at compile time: 1

start-dfs.sh和start-yarn.sh
启动所有的datanode，namenode，resourcemanager等。集群运行正常，问题似乎仅在于作业。我可以在 http://master:50070看到所有数据节点可用，在 http://master:8088看到一个工作历史页面

如果您需要其他日志或配置文件，请告诉我。
谢谢。

最佳答案

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>

mapreduce.job.tracker似乎不是有效的属性。
而且我也改变了我的 HADOOP_HOME=/home/huser/hadoop-2.7.1/到 HADOOP_HOME=/home/huser/hadoop-2.7.1删除正斜杠 (/)。

我也将hive-site.xml更改为以下内容:

<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>
      <value>thrift://master:9083</value>
    </property>
</configuration>
