hive安装

hive hadoop 安装 配置

1. 安装文件

上传文件apache-hive-2.3.3-bin.tar.gz到/opt/hadoop下

解压

tar -xzvf apache-hive-2.3.3-bin.tar.gz

1. 设置环境变量

vi /etc/profile

export HIVE_HOME=/opt/hadoop/apache-hive-2.3.3-bin

export PATH=$PATH:$HIVE_HOME/bin

enter description here

查看hive版本

hive --version

1. 修改配置文件

修改hive-site.xml文件

cd /opt/hadoop/apache-hive-2.3.3-bin/conf

cp hive-default.xml.template hive-site.xml

vi hive-site.xml

<property>

    <name>javax.jdo.option.ConnectionUserName</name>

    <value>hive</value>

    <description>Username to use against metastore database</description>

</property>

<property>

    <name>javax.jdo.option.ConnectionPassword</name>

    <value>hive</value>

    <description>password to use against metastore database</description>

</property>

<property>

    <name>javax.jdo.option.ConnectionURL</name>

    <value>jdbc:mysql://172.18.12.2:3306/hive</value>

</property>

<property>

    <name>javax.jdo.option.ConnectionDriverName</name>

    <value>com.mysql.jdbc.Driver</value>

    <description>Driver class name for a JDBC metastore</description>

</property>

修改hive-env.sh文件

cp hive-env.sh.template hive-env.sh

vi hive-env.sh

HADOOP_HOME=/opt/hadoop/hadoop-2.8.5

1. 连接mysql

复制mysql的驱动程序到hive/lib下面

创建mysql的元数据库

schematool -dbType mysql -initSchema

hadoop fs -mkdir /user/hive

hadoop fs -chown hive:hadoop /user/hive

启动hvie

运行hive之前首先要确保meta store服务已经启动，

nohup hive --service metastore > metastore.log 2>&1 &

启动hive service

nohup hive --service hiveserver2 > hiveserver2.log 2>&1 &

hive

通过beeline连接

beeline -u jdbc:hive2://172.18.12.1:10000/default -n hive

访问web

http://172.18.12.1:10002/

2. 报错处理

Exception in thread "main" java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path in absolute URI: ${system:java.io.tmpdir%7D/$%7Bsystem:user.name%7D

解决方案：将hive-site.xml配置文件的

hive.querylog.location

hive.exec.local.scratchdir

hive.downloaded.resources.dir

三个值（原始为$标识的相对路径）写成绝对值/var/log/hadoop/hive

User: hive is not allowed to impersonate hive (state=08S01,code=0)

解决方案：

修改core-site.xml文件

<property>

    <name>hadoop.tmp.dir</name>

    <value>/u01/hadoop/tmp</value>

    <description>Abase for other temporary directories.</description>

  </property>

  <property>

    <name>hadoop.proxyuser.hive.hosts</name>

    <value>*</value>

  </property>

  <property>

    <name>hadoop.proxyuser.hive.groups</name>

   <value>*</value>

  </property>
