5 远程模式安装

5.1 下载

https://hive.apache.org/

5.2 解压并重命名

tar -zxvf apache-hive-3.1.2-bin.tar.gz -C /opt/module/
cd /opt/module/
mv mv apache-hive-3.1.2-bin hive

5.3 解决hadoop、hive 之间的guava版本差异问题

 cd /opt/module/hive/librm -f guava-19.0.jarcp /opt/module/hadoop-3.1.3/share/hadoop/common/lib/guava-27.0-jre.jar ./guava-27.0-jre.jar

5.4 添加环境变量

vi /etc/profile.d/my_env.sh

 #HIVE_HOMEexport HIVE_HOME=/opt/module/hiveexport PATH=$PATH:$HIVE_HOME/bin

source /etc/profile

5.5 hive-env.sh 修改Hive环境变量

cd /opt/module/hive/conf
mv hive-env.sh.template hive-env.sh
vim hive-env.sh

# Set HADOOP_HOME to point to a specific hadoop install directory
export HADOOP_HOME=/opt/module/hadoop-3.1.3# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/opt/module/hive/conf# Folder containing extra libraries required for hive compilation/execution can be controlled by:
export HIVE_AUX_JARS_PATH=/opt/module/hive/lib

5.6 hive-log4j2.properties 日志配置

mkdir -P /opt/module/hive/datas
cd /opt/module/hive/conf
mv hive-log4j2.properties.template hive-log4j2.properties
vim hive-log4j2.properties

property.hive.log.dir = /opt/module/hive/datas

5.7 hive-site.xml 配置MateStore

添加了hive.metastore.uris 配置，则需要手动启动Matastore服务

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

</configuration>

5.8 上传mysql-connector-java-5.1.27-bin.jar

基于mysql的版本上传jar

 /opt/module/hive/lib/mysql-connector-java-5.1.27-bin.jar

5.9 初始化Matedata

cd /opt/module/hive/bin
./schematool -dbType mysql  -initSchema  --verbose

3.5.10 启动MateStore脚本

vim hive_metastore.sh

#!/bin/bash
if [ $# -lt 1 ]; thenecho "No Args Input..."exit
ficase $1 in
"start"){echo "----------------- MetaStore start -----------------"nohup /opt/module/hive/bin/hive --service metastore >> /opt/module/hive/datas/metastore.out 2>&1 &echo "----------------- Hiveserver2 start -----------------"nohup /opt/module/hive/bin/hive --service hiveserver2 >> /opt/module/hive/datas/hiveserver2.out 2>&1 &};;
"stop"){echo "----------------- MetaStore stop -----------------"pidMetaStore=$(ps -ef | grep -v grep | grep "Dproc_metastore" | awk '{printf $2" "}')kill -9 ${pidMetaStore}echo "----------------- Hiveserver2 stop -----------------"pidHiveserver2=$(ps -ef | grep -v grep | grep "Dproc_hiveserver2" | awk '{printf $2" "}')kill -9 ${pidHiveserver2}};;
*)echo "Input Args Error...";;
