hive on tez配置

1、Tez简介

Tez是Hontonworks开源的支持DAG作业的计算框架，它可以将多个有依赖的作业转换为一个作业从而大幅提升MapReduce作业的性能。Tez并不直接面向最终用户——事实上它允许开发者为最终用户构建性能更快、扩展性更好的应用程序

2、编译tez

本文记录Tez 0.8.5的编译过程，之前的Tez版本都是源码包，最新的版本虽然提供了编译后的tar包，但是大部分情况下是针对特定的Hadoop版本，如果和我们的Hadoop版本不一致，可能某个时刻会出现一些未知的问题，所以为了稳定，还是建议和自己使用的Hadoop版本匹配，所以就需要编译了。

（1）解压完毕，修改根目录下的pom.xml，修改对应的Hadoop的版本。

（2）注释掉tez-ui2的子项目依赖pom，因为tez ui2编译坑比较多，可能通不过

<modules>
     <module>hadoop-shim</module>
     <module>tez-api</module>
     <module>tez-common</module>
     <module>tez-runtime-library</module>
     <module>tez-runtime-internals</module>
     <module>tez-mapreduce</module>
     <module>tez-examples</module>
     <module>tez-tests</module>
     <module>tez-dag</module>
     <module>tez-ext-service-tests</module>
     
     <module>tez-plugins</module>
     <module>tez-tools</module>
     <module>hadoop-shim-impls</module>
     <module>tez-dist</module>
     <module>docs</module>
   </modules>

（3）如果你是root用户编译Tez，记得修改tez-ui/pom.xml，添加允许root权限执行nodejs安装bower

<execution>
             <id>Bower install</id>
             <phase>generate-sources</phase>
             <goals>
               <goal>exec</goal>
             </goals>
             <configuration>
               <workingDirectory>${webappDir}</workingDirectory>
               <executable>${node.executable}</executable>
               <arguments>
                 <argument>node_modules/bower/bin/bower</argument>
                 <argument>install</argument>
                 <argument>--allow-root</argument>
                 <argument>--remove-unnecessary-resolutions=false</argument>
               </arguments>
             </configuration>
           </execution>

（4）注意编译的linux机器最好能fan qiang下载东西，如果不能就把根目录下的pom.xml中tez-ui也注释掉，因为不管是tez-ui还是tez-ui2都需要下载nodejs相关的东西，默认的是在墙外的，不能fan出去80%的几率会编译失败，所以如果是nodejs相关的编译失败，就把tez-ui相关的子项目都注释掉不让参与编译，这个ui没什么大的作用，就是看下job的计划，没有它也能使用Tez优化DAG依赖。

（5）能不能自己在linux上单独装nodejs，然后让tez的nodejs用本机装的那个而避免下载墙外的，经实测发现不行，tez里面的nodejs好像是单独依赖的，只要编译就会下载，最好的办法就是注释掉和tez-ui相关的东西

上面的一切搞定后，开始执行编译命令：

mvn clean package -DskipTests=true -Dmaven.javadoc.skip=true

编译成功后，出现下图：

编译成功后的文件在tez-dist/target目录下：

cd /mnt/apache-tez-0.8.5-src/tez-dist/target

$ ls

archive-tmp

maven-archiver

tez-0.8.5

tez-0.8.5-minimal

tez-0.8.5-minimal.tar.gz

tez-0.8.5.tar.gz

tez-dist-0.8.5-tests.jar

3、配置hive on tez

将tez-0.8.5下所有jar包cp到hive lib/目录下，将tez-0.8.5.tar.gz上传到hdfs一个目录下：

$ /opt/cdh5/hadoop-2.6.0-cdh5.10.0/bin/hdfs dfs -mkdir -p /user/hadoop

$ /opt/cdh5/hadoop-2.6.0-cdh5.10.0/bin/hdfs dfs -put /home/hadoop/tez-0.8.5.tar.gz /user/hadoop

编辑tez配置文件etc/hadoop/tez-site.xml：

<?xml version="1.0" encoding="UTF-8"?>

<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

<configuration>
         <property>
                 <name>tez.lib.uris</name>
                 <value>/user/hadoop/tez-0.8.5.tar.gz</value>
         </property>

</configuration>

重启hadoop集群。

set hive.execution.engine=tez;

select count(*) from t1;

注意点：

本次测试我安装了cdh5.10.0的hive，部署上述tez包，运行程序报错，具体错误见下文。

将tez部署到hive 2.1.0上运行成功，结果如下：

--测试结果：
