安装HIVE 过程中要注意
1,mysql 是否正常运行
2. 创建好mysql 用户并分配好相应的访问权限以及数据库端口号等
3. mysql-connector-java-5.1.26-bin.jar 是否放到hive/lib 目录下 建议修改权限为777 (chmod 777 mysql-connector-java-5.1.26-bin.jar)
4. 修改conf/hive-site.xml 中的 “hive.metastore.schema.verification” 值为 false 即可解决 “Caused by: MetaException(message:Version information not found in metastore. )”
5. 调试 模式命令 hive -hiveconf hive.root.logger=DEBUG,console
- <property>
- <name>hive.metastore.schema.verification</name>
- <value>false</value>
- <description>
- Enforce metastore schema version consistency.
- True: Verify that version information stored in metastore matches with one from Hive jars. Also disable automatic
- schema migration attempt. Users are required to manully migrate schema after Hive upgrade which ensures
- proper metastore schema migration. (Default)
- False: Warn if the version information stored in metastore doesn't match with one from in Hive jars.
