hive-0.12升级成hive 0.13.1

来源：互联网发布：升级php的编译器编辑：程序博客网时间：2024/04/28 07:32

安装了0.12之后，听说0.13.1有许多新的特性，包括永久函数，所以想更新成0.13版的（元数据放在mysql中）

2014年8月5日实验成功

hive0.13.1的新特性

新特性详见

http://zh.hortonworks.com/blog/announcing-apache-hive-0-13-completion-stinger-initiative/

1.下载0.13.1压缩包

地址http://mirrors.hust.edu.cn/apache/hive/

打开后有

点开hive-0.13.1,有如下两个文件

下载apache-hive-0.13.1-bin.tar.gz即可，而src.tar.gz是源代码压缩包，不用下载，

2.解压压缩包

sudo tar xzvf apache-hive-0.13.1-bin.tar.gz -C /opt 我解压到了/opt下

3.执行升级脚本进行mysql元数据库的升级

执行以下命令

cd /opt/apache-hive-0.13.1-bin/scripts/metastore/upgrade/mysql
ls

在文件夹下有如下文件
001-HIVE-972.mysql.sql hive-schema-0.13.0.mysql.sql
002-HIVE-1068.mysql.sql hive-schema-0.3.0.mysql.sql

hive-schema-0.11.0.mysql.sql upgrade.order.mysql
hive-schema-0.12.0.mysql.sql

其中有upgrade-0.12.0-to-0.13.0.mysql.sql

用hive用户登录mysql(hive 0.12.0的用户)

mysql-h localhost -u hive -p

执行upgrade-0.12.0-to-0.13.0.mysql.sql脚本

mysql> use hive
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> source upgrade-0.12.0-to-0.13.0.mysql.sql

成功完成

4.在mysql中新创建一个用户hivenew给hive0.13.1用

root用户登录mysql创建hive用户并授权，执行命令：
use mysql;
insert into user(Host,User,Password)values("localhost","hivenew",password("hivenew"));密码也是hivenew

GRANTALL PRIVILEGES ON *.* TO 'hivenew'@'localhost' IDENTIFIED BY 'hivenew';

FLUSH PRIVILEGES;

可以用hivenew用户登录观察是否创建用户成功

授予用户hive足够大的权限

GRANT ALL PRIVILEGES ON *.* TO'hive'@'localhost' IDENTIFIED BY 'hive';
FLUSH PRIVILEGES;

可以用hive用户登录观察是否创建用户成功

hadoop@ubuntu:/usr/local$ mysql -h localhost -uhive -p

5.将mysql的 jdbc拷贝到apache-hive-0.13.1-bin/lib文件夹下

cp mysql-connector-java-5.1.31/*.jar apache-hive-0.13.1-bin/lib (这个jar包hive .12.0版本时已经配置好了)

6.开始配置文件

千万不可以把0.12.0的文件直接复制过来，会导致无法成功

首先复制配置文件

hadoop@ubuntu:/usr/local/hadoop/hive/conf$cphive-default.xml.template hive-default.xml
hadoop@ubuntu:/usr/local/hadoop/hive/conf$cp hive-default.xml.templatehive-site.xml
hadoop@ubuntu:/usr/local/hadoop/hive/conf$cp hive-env.sh.template hive-env.sh

hadoop@ubuntu:/usr/local/hadoop/hive/conf$cp hive-log4j.properties.template hive-log4j.properties

再创建存储目录

hadoop@ubuntu:/usr/local/hadoop/hive$mkdir -p /usr/local/hadoop/hive-0.13.1/warehouse

hadoop@ubuntu:/usr/local/hadoop/hive$mkdir -p /usr/local/hadoop/hive-0.13.1/log

然后配置hive-env.sh文件

用vim打开

将exportHADOOP_HEAPSIZE=1024前面的‘#’去掉，当然可以根据自己的环境对这个默认的1024进行优化；

把#去掉使得改动生效

将exportHADOOP_HOME前面的‘#’号去掉，并让它指向您所安装hadoop的目录，我的/usr/local/hadoop;

将exportHIVE_CONF_DIR=/opt/apache-hive-0.13.1-bin 并且把‘#’号去掉;

将exportHIVE_AUX_JARS_PATH=/opt/apache-hive-0.13.1-bin/lib,并且把‘#’号去掉。

esc(键) :wq

配置hive-site.xml,改以下几个地方

<property> <name>hive.metastore.warehouse.dir</name> <value>/usr/local/hadoop/hive-0.13.1/warehouse</value>//与上面创建的文件夹一致 <description>location of default database for thewarehouse</description></property>  #存放hive相关日志的目录<property> <name>hive.querylog.location</name>  <value>/usr/local/hadoop/hive-0.13.1/log</value>  <description>    Location of Hive run time structured log file  </description></property>接着修改hive-site.xml 这一步将mysql与hive连接<property>  <name>hive.metastore.local</name>  <value>true</value></property> <property> <name>javax.jdo.option.ConnectionURL</name> <value>jdbc:mysql://localhost:3306/hivenew?createDatabaseIfNotExist=true</value>//这次新创建的元数据库是hivemew  <description>JDBC connect string for aJDBC metastore</description></property> <property> <name>javax.jdo.option.ConnectionDriverName</name> <value>com.mysql.jdbc.Driver</value>  <description>Driver class name for aJDBC metastore</description></property> <property> <name>javax.jdo.option.ConnectionUserName</name>  <value>hivenew</value>//用新创建的用户  <description>username to use againstmetastore database</description></property> <property>  <name>javax.jdo.option.ConnectionPassword</name>  <value>hivenew</value>  <description>password to use againstmetastore database</description></property></span>

<pre name="code" class="html"> <property>   <name>hive.stats.dbclass</name>  <value>jdbc:mysql</value>  <description>The default database that stores temporary hive statistics.</description>  </property>   <property>   <name>hive.stats.jdbcdriver</name>   <value>com.mysql.jdbc.Driver</value> <description>The JDBC driver for the database that stores temporary hive statistics.</description>  . </property>  <property>  <name>hive.stats.dbconnectionstring</name>  <value>jdbc:mysql://localhost:3306/hivenew</value>  description>The default connection string for the database that stores temporary hive statistics.</description>  </property>

另外为了避免启动时发生警报，所以把hive.metastore.ds.retry打头的都换成 hive.hmshandler.retry（retry后面不动）

7.激动人心的时刻到了，启动hive

bin/hive

再看看mysql里有没有元数据库

mysql -h localhost -u hivenew -p

hive 0.13.1竟然只有29个表,hive-0.12.0有40个表呢

更新成功！！！

8.要安装hive 0.13.1网络接口的见我的另外一篇博客
