Hive On Tez

1. Download Tez

wget http://www-us.apache.org/dist/tez/0.9.2/apache-tez-0.9.2-bin.tar.gz

2, the configuration Tez

1) The $ TEZ_HOME / share / tez.tar.gz uploaded to HDFS: hdfs: ///cdh5/apps/tez/tez.tar.gz.

hdfs dfs -mkdir -p /cdh5/apps/tez
hdfs dfs -put /opt/cloudera/tez-0.9.2/share/tez.tar.gz /cdh5/apps/tez

2) Configuration tez-site.xml at $ TEZ_HOME / conf:

<configuration>
	<property>
		<name>tez.lib.uris</name>
		<value>hdfs:///cdh5/apps/tez/tez.tar.gz</value>
	</property>
	<property>
		<name>tez.use.cluster.hadoop-libs</name>
		<value>true</value>
	</property>
	<property>
		<name>tez.runtime.compress</name>
		<value>true</value>
	</property>
	<property>
		<name>tez.runtime.compress.codec</name>
		<value>org.apache.hadoop.io.compress.SnappyCodec</value>
	</property>
</configuration>

Copy the $ TEZ_HOME / conf / tez-site.xml to "$ HADOOP_HOME / etc / hadoop" directory for all nodes.

3) Configuration Hive

$ HIVE_HOME / conf / hive-env.sh, add the following:

export TEZ_HOME=/opt/cloudera/tez
export TEZ_CONF_DIR=$TEZ_HOME/conf
export HADOOP_CLASSPATH=${TEZ_HOME}/*:${TEZ_HOME}/lib/*:${TEZ_CONF_DIR}:${HADOOP_CLASSPATH}

$ HIVE_HOME / conf / tez-site.xml, which reads as follows:

         <value>hdfs:///cdh5/apps/tez/tez.tar.gz</value>
      </property>
</configuration>

$ HIVE_HOME / conf / hive-site.xml, modified as follows:

<property>
	<name>hive.tez.container.size</name>

</property>
<property>
	<name>hive.tez.cpu.vcores</name>

</property>
<property>
    <name>hadoop.embedded.local.mode</name>
    <value>false</value>
</property>

4) the environment variables (all nodes)

export TEZ_HOME=/opt/cloudera/tez
export TEZ_CONF_DIR=$TEZ_HOME/conf

$HADOOP_HOME/etc/hadoop/hadoop-env.sh设置"HADOOP_CLASSPATH"

export HADOOP_CLASSPATH=${TEZ_CONF_DIR}:${TEZ_HOME}/*:${TEZ_HOME}/lib/*:${HADOOP_CLASSPATH}
