无法在 Apache Tez 上运行

Question

感谢您通过屏幕截图详细发布此内容，因为 well.I 已按照您提到的相同步骤进行操作，但我无法安装 properly.The 我遇到的错误是

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

我已经下载了tez的构建版本。 Apache Tez Version:0.8.4，Hadoop Version: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 PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_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>

当我尝试运行示例示例程序时，它返回跟踪为

当我在 stderr 下的 http://localhost:8088 中看到时，我找到了上面那个。

请提前帮我解决this.Thanks！！

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 版本的详细步骤可以参考下面link。

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

虽然构建它会在 tez-ui.Inorder 上失败，但不要面对这个问题，请在您的 linux 机器上安装 git、节点 js 和 npm，然后开始构建，这将允许你构建成功。

除了上述步骤外，您还需要在~/.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。

你在 hdfs 中输入了错误的 tez 包。

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
