Question

感谢您通过屏幕截图详细发布。我已按照您提到的相同步骤进行操作，但我无法正确安装。我遇到的错误是

错误：无法找到或加载主类org.apache.tez.dag.app.DAGAppMaster

我已经下载了tez的构建版本。 Apache Tez版本：0.8.4，Hadoop版本：2.6.0。

我的tez-site.xml是

    <?xml version="1.0" encoding="UTF-8"?>
    <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
    <configuration>
    <property>
    <name>tez.lib.uris</name>
    <value>${fs.defaultFS}/apps/tez-0.8.4,${fs.defaultFS}/apps/tez-0.8.4/lib/</value>
    </property>
    </configuration>

我的bashrc配置是：

    export HADOOP_HOME=/usr/local/hadoop
    export HADOOP_INSTALL=$HADOOP_HOME
    export HADOOP_MAPRED_HOME=$HADOOP_HOME
    export HADOOP_COMMON_HOME=$HADOOP_HOME
    export HADOOP_HDFS_HOME=$HADOOP_HOME
    export YARN_HOME=$HADOOP_HOME
    export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
    export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin
    export PATH=$PATH:/usr/local/spark/bin
    export HIVE_HOME=/usr/local/hive
    export PATH=$PATH:$HIVE_HOME/bin
    export CLASSPATH=$CLASSPATH:/usr/local/Hadoop/lib/*:.

    export PATH=$PATH:$DERBY_HOME/bin

    export HIVE_OPTS="-hiveconf mapreduce.map.memory.mb=4096 -hiveconf mapreduce.reduce.memory.mb=5120"
    export TEZ_HOME=/usr/local/apache-tez-0.8.4-bin
    export TEZ_CONF_DIR=$TEZ_HOME/conf
    export TEZ_JARS=$TEZ_HOME

    if [ -z "$HIVE_AUX_JARS_PATH" ]; then
    export HIVE_AUX_JARS_PATH="$TEZ_JARS"
    else
    export HIVE_AUX_JARS_PATH="$HIVE_AUX_JARS_PATH:$TEZ_JARS"
    fi

    export HADOOP_CLASSPATH=${TEZ_CONF_DIR}:${TEZ_JARS}/*:${TEZ_JARS}/lib/*
    export CLASSPATH=$CLASSPATH:${TEZ_CONF_DIR}:${TEZ_JARS}/*:${TEZ_JARS}/lib/*:.

我的mapreduce-site.xml是

    <configuration>
       <!--<property>
          <name>mapreduce.framework.name</name>
          <value>yarn</value>
       </property> -->
       <property>
        <name>mapreduce.framework.name</name>
        <value>yarn-tez</value>
        <description>The runtime framework for executing MapReduce jobs.
                Can be one of local, classic or yarn.
        </description>
        </property>
    </configuration>

当我尝试运行示例程序时，它将跟踪返回为

当我在stderr下面的http://localhost:8088看到我找到了上面的那个。

请帮我解决这个问题。谢谢你提前!!。

由于Tez是一个孵化器项目，我们需要下载src并使用maven构建。

Tez 0.8.1 alpha版本的详细步骤可参考以下链接。

https://acadgild.com/blog/integrating-apache-tez-with-hadoop/

虽然构建它会在tez-ui失败。为了不面对这个问题，在你的linux机器上安装git，node js和npm，然后开始构建，这将允许你成功构建。

除了上面提到的步骤，还需要在〜/ .bashrc文件中添加参数

 export TEZ_CONF_DIR=/usr/local/tez/conf
 export TEZ_JARS=/usr/local/tez/tez
 export HADOOP_CLASSPATH=${TEZ_CONF_DIR}:${TEZ_JARS}/*:${TEZ_JARS}/lib/*:${HADOOP_CLASSPATH}:${JAVA_JDBC_LIBS}:${MAPREDUCE_LIBS}
 export CLASSPATH=$CLASSPATH:${TEZ_CONF_DIR}:${TEZ_JARS}/*:${TEZ_JARS}/lib/*

然后尝试运行任何成功运行的mapreduce作业。

Answer 2

你输入了错误的tez包到hdfs。

hdfs dfs -mkdir /application/tez-0.8.4

tar -zxvf apache-tez-0.8.4-bin.tar.gz

hdfs dfs -copyFromLocal apache-tez-0.8.4-bin / share / tez.tar.gz /application/tez-0.8.4

无法在Apache Tez上运行
