  # hive搭建笔记(ubuntu) 在[hadoop单机环境搭建](http://blog.csdn.net/yfkiss/article/details/7715476)成功后,可以搭建hive。 在hdfs上建目录: ~~~ $ hadoop fs -mkdir /tmp   $ hadoop fs -mkdir /user/hive/warehouse   ~~~ 添加权限: ~~~ $ hadoop fs -chmod g+w   /tmp   $ hadoop fs -chmod g+w   /user/hive/warehouse   ~~~ 下载解压hive: $ wget http://labs.mop.com/apache-mirror/hive/stable/hive-0.8.1.tar.gz . $ tar -zxvf hive-0.8.1.tar.gz 设置HADOOP_HOME、HIVE_HOME,并将其添加到~/.bashrc ~~~ export HADOOP_HOME=/home/zxm/hadoop/hadoop-1.0.3   export HIVE_HOME=/home/work/hadoop/hive-0.8.1   ~~~ 多用户支持 (确认已安装好mysql) 启动mysql: ~~~ $ mysql -u root -p mysql>grant all on hive.* to hive@localhost identified by '123456' ~~~ 修改hive conf/hive-site.xml,如下: ~~~ <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true<alue> <description>JDBC connect string for a JDBC metastore</description> </property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver<alue> <description>Driver class name for a JDBC metastore</description> </property> <property> <name>javax.jdo.option.ConnectionUserName</name> <value>hive<alue> <description>username to use against metastore database</description> </property> <property> <name>javax.jdo.option.ConnectionPassword</name> <value>123456<alue> <description>password to use against metastore database</description> </property> ~~~ 下载mysql jdbc包: wget http://downloads.mysql.com/archives/mysql-connector-java-5.0/mysql-connector-java-5.0.8.tar.gz . 解压: `tar -zxvf mysql-connector-java-5.0.8.tar.gz ` 将mysql-connector-java-5.0.8-bin.jar拷贝到hive lib目录下: cp mysql-connector-java-5.0.8/mysql-connector-java-5.0.8-bin.jar  ./lib 启动hive: `$ cd /home/zxm/hadoop/hive-0.8.1 ; ./bin/hive` 测试: ~~~ $ ./hive WARNING: org.apache.hadoop.metrics.jvm.EventCounter is deprecated. Please use org.apache.hadoop.log.metrics.EventCounter in all the log4j.properties files.
