wget http://mirror.bit.edu.cn/apache/hive/hive-0.11.0/hive-0.11.0-bin.tar.gz
tar -xzvf hive-0.11.0-bin.tar.gz
cd hive-0.11.0-bin
sudo vi /etc/profile
增加：
export HIVE_HOME=/home/ysc/hive-0.10.0-bin
export PATH=$PATH:$HIVE_HOME/bin
source /etc/profile
hadoop fs -mkdir /tmp
hadoop fs -mkdir /user/hive/warehouse
hadoop fs -chmod g+w /tmp
hadoop fs -chmod g+w /user/hive/warehouse
cp conf/hive-log4j.properties.template conf/hive-log4j.properties
如使用local模式：SET mapred.job.tracker=local;
使用HADOOP集群（默认）：SET mapred.job.tracker=host001:9001;
本地使用hive服务：
hive(如出现错误：Missing Hive Builtins Jar:/home/ysc/hive-0.11.0-bin/lib/hive-builtins-*.jar，则需要重启sudo reboot)
命令行执行HiveQL命令：创建表、准备文本数据、导入、查询
创建hive表：
create table demo (key int, value string) row format delimited fields terminated by '=' stored as textfile;
加载数据到demo 表：
load data local inpath '/home/ysc/hive-0.11.0-bin/data.txt' into table demo;
查询：
select * from demo;
select * from demo where key>=100 and key<=120;
select *,count(*) as fre from demo group by value order by fre desc;
配置Metastore使用MySQL
sudo apt-get install mysql-server mysql-client
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
sudo vi /etc/mysql/my.cnf
注释bind-address = 127.0.0.1
sudo service mysql restart
mysql -uroot -pysc
vi conf/hive-site.xml
内容为：
<?xmlversion="1.0"?>

将mysql-connector-java-5.1.18.jar放置到hive-0.10.0-bin/lib目录
启动独立Metastore服务
hive --service metastore &
启动独立Hive server服务
hive --service hiveserver &
远程使用hive服务
hive -h host001 -p 10000
启动Hive Web Interface(HWI)服务
hive --service hwi &
Hive JDBC编程
把hadoop-core-1.1.2.jar以及HIVE_HOME/lib/*.jar加入构建路径
publicstaticvoid main(String[] args) throws Exception {
Class.forName("org.apache.hadoop.hive.jdbc.HiveDriver");
Connection con = DriverManager.getConnection("jdbc:hive://host001:10000/default");
String sql = "select * from person";
PreparedStatement pst = con.prepareStatement(sql);
ResultSet rs = pst.executeQuery();
while(rs.next()){
System.out.println(rs.getString(1)+" "+rs.getString(2));
}
}
Hcatalog
sudo vi /etc/profile

hcat -e "desc test"
hcat_server.sh start & (注意不要启动后面的命令：hive --service metastore &)
hcat_server.sh stop
WebHCat(HCatalogREST API)
sudo vi /etc/profile
