...

1.下载并解压hive

cd /opt
tar -zxvf apache-hive-1.2.1-bin.tar.gz
mv apache-hive-1.2.1-bin hive-1.2.1

2.配置环境变量

vi /etc/profile

export HIVE=/opt/hive-1.2.1
export PATH=${HIVE}/bin:${PATH}

source /etc/profile

3.配置hive配置文件

3.1 修改日志文件

cp /opt/hive-1.2.1/conf/hive-log4j.properties.template /opt/hive-1.2.1/conf/hive-log4j.properties

3.2 修改hive启动环境

cp /opt/hive-1.2.1/conf/hive-env.sh.template /opt/hive-1.2.1/conf/hive-env.sh

vi /opt/hive-1.2.1/conf/hive-env.sh

export HADOOP_HOME=/opt/hadoop-2.7.1
export HIVE_CONF_DIR=/opt/hive-1.2.1/conf

3.3 修改hive启动配置

vi /opt/hive-1.2.1/bin/hive-config.sh

export JAVA_HOME=/opt/jdk1.7.0_65
export HIVE_HOME=/opt/hive-1.2.1
export HADOOP_HOME=/opt/hadoop-2.7.1

3.4 修改hive配置文件hive-site.xml

cp /opt/hive-1.2.1/conf/hive-default.xml.template /opt/hive-1.2.1/conf/hive-site.xml

vi /opt/hive-1.2.1/conf/hive-site.xml

                  <description>This is the port the Hive Web Interface will listen on</description>
         </property>
</configuration>

4.创建hive.log存放目录

mdkdir /opt/hive-1.2.1/logs

5.创建hive在HDFS上数据目录和日志目录

cd /opt/hadoop-2.7.1/bin
./hdfs dfs -ls /
./hdfs dfs -mkdir /hive
./hdfs dfs -mkdir /hive/warehouse
./hdfs dfs -mkdir /hive/scratchdir
./hdfs dfs -chmod 777 /hive/warehouse
./hdfs dfs -chmod 777 /hive/scratchdir

6.增加hive链接MySQL需要的驱动包

去MySQL官网下载mysql-connector-java-5.1.38.java
放置于/opt/hive-1.2.1/lib

7.Hadoop+hbase+hive集成相关操作，不需要集成hbase，这个可不做

cp /opt/hive-1.2.1/lib/hive-hbase-handler-1.2.1.jar                     /opt/hive-1.2.1/lib/
cp /opt/hive-1.2.1/lib/guava-14.0.1.jar                                 /opt/hive-1.2.1/lib/
cp /opt/hadoop-2.7.1/share/hadoop/hdfs/lib/protobuf-java-2.5.0.jar      /opt/hive-1.2.1/lib/
cp /opt/hbase-1.1.2/lib/hbase-client-1.1.2.jar                          /opt/hive-1.2.1/lib/
cp /opt/hbase-1.1.2/lib/hbase-common-1.1.2.jar                          /opt/hive-1.2.1/lib/
cp /opt/hadoop-2.7.1/share/hadoop/tools/lib/zookeeper-3.4.6.jar         /opt/hive-1.2.1/lib/

#同步hive的jline版本和Hadoop下版本
find /opt/hadoop-2.7.1/ -name "jline-*.jar"
/opt/hadoop-2.7.1/share/hadoop/httpfs/tomcat/webapps/webhdfs/WEB-INF/lib/jline-0.9.94.jar
/opt/hadoop-2.7.1/share/hadoop/kms/tomcat/webapps/kms/WEB-INF/lib/jline-0.9.94.jar
find /opt/hive-1.2.1/ -name "jline-*.jar"
/opt/hive-1.2.1/lib/jline-2.12.jar
cp /opt/hive-1.2.1/lib/jline-2.12.jar /opt/hadoop-2.7.1/share/hadoop/httpfs/tomcat/webapps/webhdfs/WEB-INF/lib/
cp /opt/hive-1.2.1/lib/jline-2.12.jar /opt/hadoop-2.7.1/share/hadoop/kms/tomcat/webapps/kms/WEB-INF/lib/
rm -rf /opt/hadoop-2.7.1/share/hadoop/httpfs/tomcat/webapps/webhdfs/WEB-INF/lib/jline-0.9.94.jar
rm -rf /opt/hadoop-2.7.1/share/hadoop/kms/tomcat/webapps/kms/WEB-INF/lib/jline-0.9.94.jar

8.hive服务介绍

8.1 metastore启动方式

#非后台启动
cd /opt/hive-1.2.1/bin
./hive --service metastore 

#后台启动
cd /opt/hive-1.2.1/bin
./hive --service metastore &

所有服务中metastore，必须启动，这个就像oracle 监听器一样，不过也不恰当，hive中用户自己建的表的元数据（叫啥名，有啥列）都通过这个服务存储到上面的元数据库MySQL中

8.2 hiveserver2

#非后台启动
cd /opt/hive-1.2.1/bin
./hive --service hiveserver2

#后台启动
cd /opt/hive-1.2.1/bin
./hive --service hiveserver2 &

这个服务启动主要是为了让程序通过JDBC方式连接到hive进而操作hive，所以不用程序连接，就不必要启动了，还有个要注意，老版本中服务名叫hiveserver，新版本中叫hiveserver2

8.3 hive hwi服务

这个服务就是有个hive自带的web管理界面http://192.168.202.131:9999/hwi ，让你查看hive状态，需要一个war，只有老版本有，新版本没有的

war没有的话，这么获取：

tar -zxvf apache-hive-1.2.1-src.tar.gz
cd apache-hive-1.2.1-src/hwi/web
zip hive-hwi-1.2.1.war  ./*     
cp hive-hwi-1.2.1.war /opt/hive-1.2.1/lib/

服务启动方式：

cd /opt/hive-1.2.1/bin
./hive --service hwi

启动时遇到的错误：hive NO JSP Support for /hwi, did not find org.apache.jasper.servlet.JspServlet

解决办法：1.安装ant;
          2.下载commons-el-5.5.23.jar放置于/opt/hive-1.2.1/lib下；
          3.下载jasper-compiler-5.5.23.jar放置于/opt/hive-1.2.1/lib下；
          4.下载jasper-runtime-5.5.23.jar放置于/opt/hive-1.2.1/lib下；

启动是遇到的错误：Unable to find a javac compiler; It is currently set to "/opt/jdk1.7.0_65/jre"

解决办法：
         cp /opt/jdk1.7.0_65/lib/tools.jar    /opt/hive-1.2.1/lib;

hive实战(2)hive安装和管理

博客分类： Hadoop hive 安装

8.4 hive client shell

这个就是个shell，供用户登录上去像MySQL一样操作hive

cd /opt/hive-1.2.1/bin
./hive shell

8.5 hive beeline

另一个客户端shell，启动此服务之前首先需要启动metastore和和Iveserver2，据说会取代hive client shell

[hadoopmanage@master bin]$ pwd
/opt/hive-1.2.1/bin
[hadoopmanage@master bin]$ ls
beeline  ext  hive  hive-config.sh  hiveserver2  metatool  schematool
[hadoopmanage@master bin]$ ./beeline

9.遇到的错误

9.1 集成hbase，新版本1.2.1还未解决

FAILED: Execution Error,

return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.

org.apache.hadoop.hbase.HTableDescriptor.addFamily(Lorg/apache/hadoop/hbase/HColumnDescriptor;)V

9.2 JDBC链接hive

Exception in thread "main" java.sql.SQLException: No suitable driver found for

jdbc:hive://localhost:10000/default

解决：

jdbc:hive2://localhost:10000/default不要jdbc:hive

有结果集的用resultset=stmt.executeQuery(sql);
无结果集的用stmt.execute(sql);

9.3 hive中类型我不太清楚，元数据库编码类型有点敏感，没去查MySQL中为啥要latin1,上次我元数据库为MySQL，默认编码，建表报长度越界，后来删除在MySQL上元数据库，重建元数据库，设置编码为latin1 问题解决
