1.6 Hive配置metastore
作者：互联网
一、配置
1、配置文件
#创建配置文件
[root@hadoop-senior ~]# cd /opt/modules/hive-0.13.1/conf/
[root@hadoop-senior conf]# ls
hive-default.xml.template hive-env.sh hive-exec-log4j.properties.template hive-log4j.properties.template
[root@hadoop-senior conf]# touch hive-site.xml
#
此时可以对比着hive-default.xml.template文件来修改；
hive-default.xml.template是一个模板文件；
#hive-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://hadoop-senior.ibeifeng.com:3306/metastore?createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
<description>Driver class name for a JDBC metastore</description>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>root</value>
<description>username to use against metastore database</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>123456</value>
<description>password to use against metastore database</description>
</property>
</configuration>hive-site.xml配置文件中，JDBC的配置可参考官网：https://cwiki.apache.org/confluence/display/Hive/AdminManual+Metastore+Administration
jdbc:mysql://hadoop-senior.ibeifeng.com:3306/metastore?createDatabaseIfNotExist=true
- hadoop-senior.ibeifeng.com #mysql主机名
- 3306 #mysql 端口
- metastore #存储hive元数据的库，此库不用创建，会自动生成
- createDatabaseIfNotExist=true #此句就是判断metastore库是否存在的，不存在则自动创建
另外用户名、密码是mysql的，我这里是root、123456
现在hive与mysql是在同一台服务器上；
2、拷贝mysq1驱动jar包，到Hive安装目录的1ib下
[root@hadoop-senior mysql-libs]# tar zxf mysql-connector-java-5.1.27.tar.gz [root@hadoop-senior mysql-libs]# ls MySQL-client-5.6.24-1.el6.x86_64.rpm mysql-connector-java-5.1.27 mysql-connector-java-5.1.27.tar.gz MySQL-server-5.6.24-1.el6.x86_64.rpm [root@hadoop-senior mysql-libs]# cd mysql-connector-java-5.1.27 [root@hadoop-senior mysql-connector-java-5.1.27]# ls build.xml CHANGES COPYING docs mysql-connector-java-5.1.27-bin.jar README README.txt src [root@hadoop-senior mysql-connector-java-5.1.27]# cp mysql-connector-java-5.1.27-bin.jar /opt/modules/hive-0.13.1/lib/
3、进入hive
#连接hive [root@hadoop-senior hive-0.13.1]# bin/hive Logging initialized using configuration in jar:file:/opt/modules/hive-0.13.1/lib/hive-common-0.13.1.jar!/hive-log4j.properties hive> #查看mysql库 mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | metastore | | mysql | | performance_schema | | test | +--------------------+ 5 rows in set (0.00 sec) 可见已经多了一个metastore 库，此库不用创建，是自动生成的； #hive的元数据都在metastore库中，在mysql中查看 mysql> use metastore; 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> show tables; +---------------------------+ | Tables_in_metastore | +---------------------------+ | BUCKETING_COLS | | CDS | | COLUMNS_V2 | | DATABASE_PARAMS | | DBS | | FUNCS | | FUNC_RU | | GLOBAL_PRIVS | | PARTITIONS | | PARTITION_KEYS | | PARTITION_KEY_VALS | | PARTITION_PARAMS | | PART_COL_STATS | | ROLES | | SDS | | SD_PARAMS | | SEQUENCE_TABLE | | SERDES | | SERDE_PARAMS | | SKEWED_COL_NAMES | | SKEWED_COL_VALUE_LOC_MAP | | SKEWED_STRING_LIST | | SKEWED_STRING_LIST_VALUES | | SKEWED_VALUES | | SORT_COLS | | TABLE_PARAMS | | TAB_COL_STATS | | TBLS | | VERSION | +---------------------------+ 29 rows in set (0.00 sec)
