hive 安装centos7

wget mirror.bit.edu.cn/apache/hive/hive-2.3.4/apache-hive-2.3.4-bin.tar.gz

解压到/usr/local/apache-hive

增加环境变量export HIVE_HOME=/usr/local/apache-hive

将bin加入path

cd /usr/local/apache-hive/conf

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

vim hive-site.xm

# cat hive-site.xml

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

修改

# Set HADOOP_HOME to point to a specific hadoop install directory
export HADOOP_HOME=/usr/local/hadoop/hadoop-2.7.7

# Hive Configuration Directory can be controlled by:
export HIVE_CONF_DIR=/usr/local/apache-hive/conf

# Folder containing extra libraries required for hive compilation/execution can be controlled by:
export HIVE_AUX_JARS_PATH=/usr/local/apache-hive/lib

hadoop fs -mkdir -p /user/hive/warehouse
hadoop fs -mkdir -p /user/hive/tmp
hadoop fs -mkdir -p /user/hive/log hadoop fs -chmod -R 777 /user/hive/warehouse hadoop fs -chmod -R 777 /user/hive/tmp hadoop fs -chmod -R 777 /user/hive/log
