Hadoop2.9.1 安装 Hive2.3.3 on ubuntu 16.04
前言
http://hive.apache.org/downloads.html 上有说明，hadoop3.x版本需要hive3.0.0，而hadoop2.x需要hive2.3.3。因为我的hadoop是2.9，所以选择下载hive2.3.3。Hive是hadoop的工具，所以只需要安装在NameNode上，不需要安装在DataNode上。

安装 Hive2.3.3
1、下载 Hive
# 下载地址：
wget http://mirrors.shu.edu.cn/apache/hive/stable-2/apache-hive-2.3.3-bin.tar.gz
# 解压Hive2.3.3
tar xvf apache-hive-2.3.3-bin.tar.gz -C /usr/local/
chown -R hadoop.hadoop /usr/local/apache-hive-2.3.3-bin/2、配置 Hive2.3.3 环境变量
cat << EOF >> ~/.bashrc
HIVE_HOME=/usr/local/apache-hive-2.3.3-bin
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$HADOOP_HOME/bin:$HIVE_HOME/bin:$HIVE_HOME/conf
export JAVA_HOME JRE_HOME CLASS_PATH PATH HADOOP_HOME HIVE_HOME
EOF
source /etc/profile3、配置 hive-env.sh
cat < EOF > /usr/local/apache-hive-2.3.3-bin/hive-env.sh
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export HADOOP_HOME=/usr/local/hadoop
export HIVE_HOME=/usr/local/apache-hive-2.3.3-bin
# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=$HIVE_HOME/conf
# Folder containing extra libraries required for hive compilation/execution can be controlled by:
export HIVE_AUX_JARS_PATH=$HIVE_HOME/lib/*
EOF
4、配置 hive-site.xml
Hive环境模式有3中，本例中采用了内嵌模式
cp hive-default.xml.template hive-site.xml
hive-site.xml 文件内容不需要修改，主要配置
hive.metastore.warehouse.dir
/user/hive/warehouse
location of default database for the warehouse
..
hive.exec.scratchdir
/tmp/hive
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}/<username> is created, with ${hive.scratch.dir.permission}.
注：
-
hive.metastore.warehouse.dir
该参数指定了Hive的数据存储目录，默认位置在HDFS上面的 /user/hive/warehouse路径下
-
hive.exec.scratchdir
该参数指定了Hive的数据临时文件目录，默认位置为HDFS上面的 /tmp/hive路径下
5、创建HDFS目录
hive-site.xml 文件中有两个重要的HDFS路径/user/hive/warehouse和/tmp/hive，需要在HDFS中创建，并修改权限
hadoop fs -mkdir /user
hadoop fs -mkdir /user/hive
hadoop fs -mkdir /user/hive/warehouse
hadoop fs -mkdir /tmp/hive
hadoop fs -chmod 777 /user/hive/warehouse
hadoop fs -chmod 777 /tmp/hive6、初始化数据库
内嵌模式用的是本地数据库derby
./schematool -initSchema -dbType derby

7、启动hive
进入$HIVE_HOME/bin目录
cd $HIVE_HOME/bin
./hive
# 测试
hive> show tables;
OK

在hive-site.xml文件最前面增加如下配置，重启hive
创建一个缓存目录：mkdir -p /usr/local/apache-hive-2.3.3-bin/tmpdir
system:java.io.tmpdir
/usr/local/apache-hive-2.3.3-bin/tmpdir
system:user.name
hive
