大数据的离线数据分析项目中，hive如何集入tez运行引擎

1、下载和安装tez
1）下载tez的依赖包，下载地址为：http://tez.apache.org
2）拷贝apache-tez-0.9.1-bin.tar.gz到anry2(anry2是我的主机名)的/anry/module目录下
[[email protected] module]$ ls
apache-tez-0.9.1-bin.tar.gz
3）解压缩apache-tez-0.9.1-bin.tar.gz
[[email protected] module]$ tar -zxvf apache-tez-0.9.1-bin.tar.gz
4）修改名称
[[email protected] module]$ mv apache-tez-0.9.1-bin/ tez-0.9.1

2、 在Hive中配置Tez
1）进入到Hive的配置目录：/anry/module/hive/conf
[[email protected] conf]$ pwd
/anry/module/hive/conf
2）在hive-env.sh文件中添加tez环境变量配置和依赖包环境变量配置
[[email protected] conf]$ vim hive-env.sh
添加如下配置
# Set HADOOP_HOME to point to a specific hadoop install directory
export HADOOP_HOME=/anry/module/hadoop-2.7.2

# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/anry/module/hive/conf

# Folder containing extra libraries required for hive compilation/execution can be controlled by:
export TEZ_HOME=/anry/module/tez-0.9.1    *#是你的tez的解压目录*
export TEZ_JARS=""
for jar in `ls $TEZ_HOME |grep jar`; do
    export TEZ_JARS=$TEZ_JARS:$TEZ_HOME/$jar
done
for jar in `ls $TEZ_HOME/lib`; do
    export TEZ_JARS=$TEZ_JARS:$TEZ_HOME/lib/$jar
done

export HIVE_AUX_JARS_PATH=/anry/module/hadoop-2.7.2/share/hadoop/common/hadoop-lzo-0.4.20.jar$TEZ_JARS

3）在hive-site.xml文件中添加如下配置，更改hive计算引擎

<property>
    <name>hive.execution.engine</name>
    <value>tez</value>
</property>

3、 Tez自身的配置
1）在Hive的/opt/module/hive/conf下面创建一个tez-site.xml文件
[[email protected] conf]$ pwd
/anry/module/hive/conf

[[email protected] conf]$ vim tez-site.xml
添加如下内容

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
	<name>tez.lib.uris</name>    
	<value>${fs.defaultFS}/tez/tez-0.9.1,${fs.defaultFS}/tez/tez-0.9.1/lib</value>
</property>
<property>
	<name>tez.lib.uris.classpath</name>    	
	<value>${fs.defaultFS}/tez/tez-0.9.1,${fs.defaultFS}/tez/tez-0.9.1/lib</value>
</property>
<property>
     <name>tez.use.cluster.hadoop-libs</name>
     <value>true</value>
</property>	
<property>
     <name>tez.history.logging.service.class</name>   
     <value>org.apache.tez.dag.history.logging.ats.ATSHistoryLoggingService</value>     		  		     
</property>
</configuration>

4、 上传Tez到集群中
1）将/anry/module/tez-0.9.1上传到HDFS的/tez路径
[[email protected] conf]$ hadoop fs -mkdir /tez
[[email protected] conf]$ hadoop fs -put /opt/module/tez-0.9.1/ /tez
[[email protected] conf]$ hadoop fs -ls /tez
/tez/tez-0.9.1
