Tez - 安裝

一、Tez 安裝

1 下載地址

https://mirrors.tuna.tsinghua.edu.cn/apache/tez/0.9.0/

2 二進制包安裝

2.1 解壓並重命名

[root@hadoop01 ~]# tar -zxvf /home/apache-tez-0.9.0-bin.tar.gz -C /usr/local/
[root@hadoop01 ~]# mv /usr/local/apache-tez-0.9.0-bin/ /usr/local/tez-0.9.0/

2.2 上傳tez.tar.gz到hdfs

[root@hadoop01 tez-0.9.0]# hdfs dfs -mkdir /tez-0.9.0
[root@hadoop01 tez-0.9.0]# hdfs dfs -put /usr/local/tez-0.9.0/share/tez.tar.gz /tez-0.9.0

2.3 配置環境

[root@hadoop01 ~]# vi /etc/profile

增加內容如下：

export TEZ_CONF_DIR=$HADOOP_CONF_DIR
export TEZ_JARS=/usr/local/tez-0.9.0/*:/usr/local/tez-0.9.0/lib/*
export HADOOP_CLASSPATH=$TEZ_CONF_DIR:$TEZ_JARS:$HADOOP_CLASSPATH

[root@hadoop01 ~]# source /etc/profile

2.4 創建配置tez-site.xml文件

1、
[root@hadoop01 ~]# vi /home/hadoop/apps/hadoop-2.8.5/etc/hadoop/tez-site.xml

2、
tez-site.xml文件內容如下：
<?xml version="1.0" encoding="UTF-8"?>

<configuration>
  <property>
    <name>tez.lib.uris</name>
    <value>${fs.defaultFS}/tez-0.9.0/tez.tar.gz</value>
  </property>

  <property>
    <name>tez.container.max.java.heap.fraction</name>
    <value>0.2</value>
  </property>
</configuration>

更多配置參考默認配置：/usr/local/tez-0.9.0/conf/tez-default-template.xml

2.5 Tez和Hadoop的兼容

tez下的lib目錄中的hadoop包的版本和實際安裝的hadoop版本不一定一致，需要將其jar包更換

1、刪除不符合版本的jar:
[root@hadoop01 tez-0.9.0]# rm -rf ./lib/hadoop-mapreduce-client-core-2.7.0.jar ./lib/hadoop-mapreduce-client-common-2.7.0.jar

2、重新在hadoop目錄中拷貝:
[root@hadoop01 ~]# cp /home/hadoop/apps/hadoop-2.8.5/share/hadoop/mapreduce/hadoop-mapreduce-client-common-2.8.5.jar /usr/local/tez-0.9.0/lib/

[root@hadoop01 ~]# cp /home/hadoop/apps/hadoop-2.8.5/share/hadoop/mapreduce/hadoop-mapreduce-client-core-2.8.5.jar /usr/local/tez-0.9.0/lib/

2.6 測試Tez引擎

[root@hadoop01 ~]# hive --service metastore &

[root@hadoop01 ~]# hive

hive> use xry;

hive> set hive.execution.engine=tez;

hive> select count(*) from u4 group by user_id;


hive> set hive.execution.engine=tez;

hive> select count(*) from u4 group by user_id;
