1.安装maven

1.1 下载maven

https://maven.apache.org/download.cgi

1.2上传解压

tar -zxvf apache-maven-3.6.3-bin.tar.gz -C /opt

1.3 配置 MVN_HOMR

[root@cluster2-slave2 ~]# vim /etc/profile

export MVN_HOME=/data/module/apache-maven-3.6.3
export PATH=$PATH:$MVN_HOME/bin
[root@cluster2-slave2 ~]# source /etc/profile

1.4 验证maven

[root@cluster2-slave2 ~]# mvn -v

2 安装protobuf-2.5.0.tar.gz

2.1 下载

只能是2.5.0这个版本

因为后面安装tez0.91的时候加压后在pom.xml里可以看到，要求就是2.5.0的

hadoop使用protocol buffer进行通信，需要下载和安装 protobuf-2.5.0.tar.gz。

但是现在 protobuf-2.5.0.tar.gz已经无法在官网 https://code.google.com/p/protobuf/downloads/list中 下载了

我在百度网盘找到了下载链接这里附上下载链接

链接：https://pan.baidu.com/s/1hm7D2_wxIxMKbN9xnlYWuA
提取码：haz4

2.2 上传解压

tar -zxvf protobuf-2.5.0.tar.gz

2.3 configure校验

cd protobuf-2.5.0/

[root@cluster2-slave2 protobuf-2.5.0]# ./configure

第一次我校验失败：

See `config.log' for more details

错误信息：

configure: error: in `/data/software/protobuf-2.5.0':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check

问题的根源是缺少必要的C++库。如果是CentOS系统，运行，如下命令解决

yum install glibc-headers
yum install gcc-c++ 

结束后日志：

再次检查通过

2.4 make

[root@cluster2-slave2 protobuf-2.5.0]# make

2.5 make install

[root@cluster2-slave2 protobuf-2.5.0]# make install

2.6 验证protobuf

[root@cluster2-slave2 protobuf-2.5.0]# protoc --version

libprotoc 2.5.0

可见安装成功

3 安装 Tez

3.1 下载

http://www.apache.org/dyn/closer.lua/tez/0.9.1/

下载源码自己根据自己的环境编译

3.2 上传解压

[root@cluster2-slave2 software]# tar -zxvf apache-tez-0.9.1-src.tar.gz -C …/module/

3.3 修改pom.xml

有四处修改：

（1）hadoop.version版本对应修改

确认自己的hadoop版本

修改如下

**（2）repository.cloudera

(3) 新增pluginRepository.clouder

(4) 注释不必要的东西减少下载和编译出错概率**

完整pom.xml 如下

3.4 maven编译

注意：我们不需要javadoc和test所以可以编译时跳过

所以用下面领命编译

在pom.xml同级目录下执行

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

开始编译

3.5 遇到问题

第一次编译要下载很多包有可能中途下载失败

比如下面就是一次包的依赖没有下载成功报错了

重试后所有依赖的jar下载成功

但是编译还遇到了一个问题

报ApplicationReport.newInstance() 89行异常

/data/module/apache-tez-0.9.1-src/tez-mapreduce/src/main/java/org/apache/tez/mapreduce/clienttRunningJob.java:[89,29] no s

解决办法：更换ApplicationReport.newInstance()的另一个方法

更换源代码：

return ApplicationReport.newInstance(unknownAppId, unknownAttemptId, "N/A",
        "N/A", "N/A", "N/A", 0, null, YarnApplicationState.NEW, "N/A", "N/A",
        0, 0, FinalApplicationStatus.UNDEFINED, null, "N/A", 0.0f, "TEZ_MRR", null)
 更换为新代码：

return ApplicationReport.newInstance(unknownAppId, unknownAttemptId, "N/A",
        "N/A", "N/A", "N/A", 0, null, YarnApplicationState.NEW, "N/A", "N/A",
        0, 0, 0, FinalApplicationStatus.UNDEFINED, null, "N/A", 0.0f, "TEZ_MRR", null);
vim tez-mapreduce/src/main/java/org/apache/tez/mapreduce/clienttRunningJob.java

然后继续编译

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

3.6 最后编译成功

编译后的文件在tez-dist/target下面

我的在：/data/module/apache-tez-0.9.1-src/tez-dist/target

3.7 整个tez到hdfs

hdfs上创建相应的tez目录

[root@cluster2-slave2 target]# hadoop fs -mkdir /user/tez
上传tez-0.9.1.tar.gz到 /user/tez目录

[root@cluster2-slave2 target]# hadoop fs -put tez-0.9.1.tar.gz /user/tez

3.8 整个tez到hive

（1）进入CDH lib目录

cd /opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib
(2) 创建tez相关目录目录

[root@cluster2-slave2 lib]# mkdir -p tez/conf

（3）创建 tez-site.xml文件

[root@cluster2-slave2 lib]# cd tez/conf/
[root@cluster2-slave2 conf]# vim tez-site.xml

<configuration>
  <property>
    <name>tez.lib.uris</name>
    <value>${fs.defaultFS}/user/tez/tez-0.9.1.tar.gz</value>
  </property>
  <property>
    <name>tez.use.cluster.hadoop-libs</name>
    <value>false</value>
  </property>
</configuration>

(4）tez-0.9.1-minimal拷贝到tez中

下面的目录

/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/tez

[root@cluster2-slave2 tez-0.9.1-minimal]# cp ./*.jar /opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/tez
[root@cluster2-slave2 tez-0.9.1-minimal]# cp -r lib /opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/tez

（5）分发tez这个文件到各个节点

[root@cluster2-slave2 lib]# scp -r tez root@cluster2-slave1:/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib
[root@cluster2-slave2 lib]# scp -r tez root@cluster2-master:/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib

3 配置hvie环境

3.1 配置环境

在cdh找到hive客户端配置

HADOOP_CLASSPATH=/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/tez/conf:/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/tez/*:/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/tez/lib/*

然后保存并部署客户端配置，使生效

3.2 测试效果

报错

3.3 异常处理

3.1.1 Caused by: java.lang.NullPointerException: hive.llap.daemon.service.hosts must be defined

解决办法 修改：

禁用LLAP服务。

修改hive-site.xml

设置 hive.llap.enabled=false

3.1.2 Exception: Too many counters: 121 max=120

原因是hadoop 设置counters数默认是120个
yarn 配置mapreduce.job.counters.max=2000

3.1.3 Caused by: java.lang.RuntimeException: Map operator initialization failed

原因是mapJoin是先将一张表存放在内存中进行缓存,当如果表的数据过大的时候,内存吃不消进而报错,mapJoin一把处理一张小表和一张大表,新版的hive会自动优化把小表存入内存中进行缓存.如果业务需求必须要用两张大表进行Join,那需要先把mapJoin临时关闭

sql文件中设置：set hive.auto.convert.join=false;

3.1.4 hive on tez 报错IndexOutOfBoundsException: Index: 0, Size: 0

原因是 left join 关联字段有空值导致，
处理方式一：过滤空值（关联字段）
处理方式二：set hive.auto. convert. join=false;

3.1.5 hive使用tez引擎和使用mr引擎数据量不一致

原因：

Tez和MR一样，都默认开启了mapjoin，这里面涉及到了几个参数 – 是否自动开启mapjoin,默认为true set hive.auto. convert. join=true; – mapjoin小表和大表的阈值设置 set hive.mapjoin.smalltable.filesize =25000000; – 多个mapjoin 转换为1个时，限制输入的最大的数据量 影响tez，默认10m set hive.auto. convert. join .noconditionaltask.size =10000000 ; 当表的数据大于10m时，tez会把多余的那部分数据截掉，这样就会造成丢数据。
hive3和hive2 hash算法不一致导致 参考 https://blog.csdn.net/weixin_38070561/article/details/126895259

3.4 日志太多的处理

实际上可以看出这个过程日志太多了。看着不清爽，下面的操作减少日志输出量

这是因为/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/tez/lib目录下有

slf4j-api-1.7.10.jar
slf4j-log4j12-1.7.10.jar
两个包

并且现在hive日志级别是 INFO

那么现在通过CDH控制台把hive日志级别设置成ERROR

重启hive使生效

也可以直接删除下面这两个包

slf4j-api-1.7.10.jar
slf4j-log4j12-1.7.10.jar

查看hive查询日志

这个时候yarn上也显示 ApplicationType 是 Tez

6.5 hiveserver2也配置能启用tez

set hive.tez.container.size=3020;
set hive.execution.engine=tez;

select brandid,vipid,sku_id,`time` from pro30049.add_to_cart_dt_partition where vipid=1197032 and `time`>=1588953500000 and `time`<=1589039999000;
