安装tez引擎

1.解压tez压缩包

mkdir tez
tar -zxvf tez-0.10.1-SNAPSHOT.tar.gz

2.上传tez-0.10.1-SNAPSHOT.tar.gz到hdfs

hadoop fs -put /opt/tez/tez-0.10.1-SNAPSHOT.tar.gz  /tez

3.新建tez-site.xml

vim $HADOOP-HOME/etc/hadoop/tez-site.xml

添加

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>tez.lib.uris</name>
 <value>hdfs://mycluster/tez/tez-0.10.1-SNAPSHOT.tar.gz</value>
</property>
<property>
 <name>tez.use.cluster.hadoop-libs</name>
 <value>true</value>
</property>
<property>
 <name>tez.am.resource.memory.mb</name>
 <value>1024</value>
</property>
<property>
 <name>tez.am.resource.cpu.vcores</name>
 <value>1</value>
</property>
<property>
 <name>tez.container.max.java.heap.fraction</name>
 <value>0.4</value>
</property>
<property>
 <name>tez.task.resource.memory.mb</name>
 <value>1024</value>
</property>
<property>
 <name>tez.task.resource.cpu.vcores</name>
 <value>1</value>
</property>
</configuration>

4.修改hadoop环境变量

vim  $HADOOP_HOME/etc/hadoop/shellprofile.d/tez.sh

添加tez的jar包信息

hadoop_add_profile tez
function _tez_hadoop_classpath
{
 hadoop_add_classpath "$HADOOP_HOME/etc/hadoop" after
 hadoop_add_classpath "/opt/tez/*" after
 hadoop_add_classpath "/opt/tez/lib/*" after
}

5.修改Hive的计算引擎

添加

<property>
 <name>hive.execution.engine</name>
 <value>tez</value>
</property>
<property>
 <name>hive.tez.container.size</name>
 <value>1024</value>
</property>

6.解决jar包冲突

rm /opt/tez/lib/slf4j-log4j12-1.7.10.jar

测试

完整的hive-site.xml

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
