前言

此前我写了一篇关于hive 1.2.1版本搭建的教程，参看https://www.geek-share.com/detail/2802226042.html。本篇主要讲基于hadoop3.x hive的搭建，中间的一些步骤与上篇教程一样，大家可以先看下上面链接，本篇主要描述hive3.x与历史版本搭建的不同之处。本地模式用的较少就不复赘述，直接从local模式开始，远程模式与历史版本无异，本篇也不再赘述。

一、local模式

1.修改hive-site.xml

[code]<configuration>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive_remote/warehouse</value>
</property>
<property>
<name>hive.exec.scratchdir</name>
<value>/tmp/hive</value>
<description>HDFS root scratch dir for Hive jobs which gets created with write all (733) permission. For each connecting user, an HDFS scratch dir: ${hive.exec.scratchdir}/&lt;username&gt; is created, with ${hive.scratch.dir.permission}.</description>
</property>
<property>
<name>hive.exec.local.scratchdir</name>
<value>/opt/software/hive/temp/root</value>
</property>
<property>
<name>hive.downloaded.resources.dir</name>
<value>/opt/software/hive/temp/${hive.session.id}_resources</value>
</property>
<property>
<name>hive.server2.logging.operation.log.location</name>
<value>/opt/software/hive/temp/root/operation_logs</value>
</property>

<property>
<name>hive.querylog.location</name>
<value>/opt/software/hive/temp/root</value>
</property>
<property>
<name>hive.metastore.local</name>
<value>true</value>
</property>

<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost/hive_meta?createDatabaseIfNotExist=true</value>
</property>

<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>

<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hive</value>
</property>

<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>123</value>
</property>
</configuration>

2.修改hive-env.sh

[code]export HADOOP_HOME=/opt/software/hadoop

export HIVE_CONF_DIR=/opt/software/hive/conf

export HIVE_AUX_JARS_PATH=/opt/software/hive/lib

3.将hadoop/share/hadoop/common/lib 下的 guava-xx.jar 复制到hive/lib 下 将hive 的guava-xx.jar删除

4.大功告成了，赶快试试吧！
