apache-hive-1.2.1-bin 安装

更多资源:https://github.com/opensourceteams

技能标签

  • 下载apache hive 安装包
  • 进行apache-hive-1.2.1-bin.tar.gz安装
  • 配置mysql存储元数据
  • 配置HDFS存储 /user/hive/warehouse
  • 该Hive版本1.2.1默认集成在(Spark1.6 到 Spark2.4)

下载

  • 下载安装包apache-hive-1.2.1-bin.tar.gz: https://archive.apache.org/dist/hive/hive-1.2.1
  • 由于spark-2.4.0-bin-hadoop2.7 预编译好的捆绑hive版本为hive-1.2.1,为了方便所以选用版本apache-hive-1.2.1-bin
  • 如果spark支持其它版本的hive,需要重新手动编译spark源码也可以实现

安装

解压安装包

tar -zxvf apache-hive-1.2.1-bin.tar.gz -C /opt/module/bigdata/

配置环境变量

export HIVE_HOME=/opt/module/bigdata/apache-hive-1.2.1-bin
export PATH=$HIVE_HOME/lib:#PATH

HDFS新建目录

bin/hadoop fs -mkdir -p /user/hive/warehouse #创建目录
bin/hadoop fs -chmod -R 777 /user/hive/warehouse #新建的目录赋予读写权限
bin/hadoop fs -mkdir -p /tmp/hive/#新建/tmp/hive/目录
bin/hadoop fs -chmod -R 777 /tmp/hive #目录赋予读写权限
#用以下命令检查目录是否创建成功
bin/hadoop fs -ls /user/hive
bin/hadoop fs -ls /tmp/hive

连接mysql数据库

  • 复制jdbc连接驱动
cp mysql-connector-java-8.0.13.jar $HIVE_HOME/lib/

新建hive-site.xml数据库相关的配置

  • touch hive-site.xml文件
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hive.metastore.warehouse.dir</name>

# Set Hive and Hadoop environment variables here. These variables can be used
# to control the execution of Hive. It should be used by admins to configure
# the Hive installation (so that users do not have to set environment variables
# or set command line parameters to get correct behavior).
#
# The hive service being invoked (CLI/HWI etc.) is available via the environment
# variable SERVICE
# Hive Client memory usage can be an issue if a large number of clients
# are running at the same time. The flags below have been useful in
# reducing memory usage:
#
# if [ "$SERVICE" = "cli" ]; then
# if [ -z "$DEBUG" ]; then
# export HADOOP_OPTS="$HADOOP_OPTS -XX:NewRatio=12 -Xms10m -XX:MaxHeapFreeRatio=40 -XX:MinHeapFreeRatio=15 -XX:+UseParNewGC -XX:-UseGCOverheadLimit"
# else
# export HADOOP_OPTS="$HADOOP_OPTS -XX:NewRatio=12 -Xms10m -XX:MaxHeapFreeRatio=40 -XX:MinHeapFreeRatio=15 -XX:-UseGCOverheadLimit"
# fi
# fi
# The heap size of the jvm stared by hive shell script can be controlled via:
#
# export HADOOP_HEAPSIZE=1024
#
# Larger heap size may be required when running queries over large number of files or partitions.
# By default hive shell scripts use a heap size of 256 (MB). Larger heap size would also be
# appropriate for hive server (hwi etc).
# Set HADOOP_HOME to point to a specific hadoop install directory
# HADOOP_HOME=${bin}/../../hadoop
# Hive Configuration Directory can be controlled by:
# export HIVE_CONF_DIR=
# Folder containing extra ibraries required for hive compilation/execution can be controlled by:
# export HIVE_AUX_JARS_PATH=
HADOOP_HOME=/opt/module/bigdata/hadoop-2.9.2
export HIVE_CONF_DIR=/opt/module/bigdata/apache-hive-1.2.1-bin/conf
export HIVE_AUX_JARS_PATH=/opt/module/bigdata/apache-hive-1.2.1-bin/lib

初使化元数据数据库

schematool -initSchema -dbType mysql

启动hive

hive
  • hive启动说明

「图文」apache-hive-1.2.1-bin 安装

启动hive metastore服务

  • 启动该服务会开一个 9083端口
  • netstat -ntlup 可以查看服务端占用的端口
hive --service metastore & 

「图文」apache-hive-1.2.1-bin 安装

停止hive metastore服务

ps -ef|grep hive
kill -9 pid

启动hiveserver服务 (该服务可以不启动)

hive --service hiveserver2 & 

操作

启动 hive

hive

退出 hive命令

exit;

创建database

create database;

显示所有的database

show databases;

显示所有的表

show tables;

创建表

CREATE TABLE IF NOT EXISTS employee ( name String, salary String) COMMENT 'Employee details' ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n' STORED AS TEXTFILE;

插入数据

  • 数据文件 employee.txt
小明 100000
小王 50000
小李 60000
  • 插入数据文件到hive上
LOAD DATA LOCAL INPATH '/home/liuwen/temp/employee.txt' OVERWRITE INTO TABLE employee;

查看表数据

 select * from employee;

问题处理

无法访问spark-assembly-*.jar


[liuwen@standalone lib]$ schematool -initSchema -dbType mysql
