hive&mysql安装配置

1）安装mysql,不提了
sudo start mysql
sudo stop mysql
mysql -u root -p

2） 下载一个数据包mysql-connector-java-5.1.18-bin.jar，放到hive的lib目录下

3）将hive/conf下的hive-default.xml.template复制并改名为hive-site.xml。配置如下（原来里面内容很多，全部删除）：

<configuration><property><name>javax.jdo.option.ConnectionURL</name><value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true</value></property><property><name>javax.jdo.option.ConnectionDriverName</name><value>com.mysql.jdbc.Driver</value></property><property><name>javax.jdo.option.ConnectionUserName</name><value>root</value></property><property><name>javax.jdo.option.ConnectionPassword</name><value>111111</value></property></configuration>

4）hive-env.sh两行内容改为：

# Set HADOOP_HOME to point to a specific hadoop install directory HADOOP_HOME=/home/cc/software/hadoop-2.5.1

5）启动hive,出错：

原因是hadoop太旧，hive太新。

解决方法：将hive下的新版本jline的JAR包拷贝到hadoop下：
hadoop目录下老版本jline：
/hadoop-2.5.2/share/hadoop/yarn/lib/jline-0.9.94.jar

hive下的新版本jline：
/hive/apache-hive-1.1.0-bin/lib/jline-2.12.jar
