auxService:mapreduce_shuffle 配置单元上不存在

Question

我使用的是 hive 1.2.0 和 hadoop 2.6.0。每当我在我的机器上运行蜂巢时... select 查询工作正常但在 count(*) 的情况下它显示以下错误：

Answer 1

请在yarn-site.xml中使用这个；当您将框架设置为用作 yarn 时，它会开始查找这些值。

<configuration>
  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
  </property>
  <property>
    <name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
    <value>org.apache.hadoop.mapred.ShuffleHandler</value>
  </property>
</configuration>

当您将框架设置为用作 yarn 时，它会开始查找这些值。 Java Map reduce 我遇到了同样的错误。当我将配置设置如下时：

Configuration conf = new Configuration();
conf.set("mapreduce.framework.name", "yarn");

我通过以下设置解决了它：

<configuration>

<!-- Site specific YARN configuration properties -->


<property>
               <name>yarn.nodemanager.aux-services</name>
               <value>mapreduce_shuffle</value>
</property>
<property>
    <name>yarn.nodemanager.aux-services.mapreduce_shuffle.class</name>
    <value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>

</configuration>
