起因是我重装了mysql数据库。

安装之后把访问权限都配置好：

GRANT ALL PRIVILEGES ON*.* TO 'hive'@'%' Identified by 'hive';
GRANT ALL PRIVILEGES ON*.* TO 'hive'@'localhost' Identified by 'hive';
GRANT ALL PRIVILEGES ON*.* TO 'hive'@'127.0.0.1' Identified by 'hive';
本机地址： 192.168.103.43 机器名字：192-168-103-43
flush privileges;

启动hive 发生下面的错误：

hive> show tables;

FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClientFAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

cd ${HIVE_HOME}/bin

./hive -hiveconf hive.root.logger=DEBUG,console

hive> show tables;

得到如下的错误信息(当然不同的问题所产生的日志是不同的)：

发现数据库的权限 HIVE需要的是

'hive'@'192-168-103-43' 这个IP地址

然后试着在mysql中加上权限：

GRANT ALL PRIVILEGES ON*.* TO 'hive'@'192-168-103-43' Identified by 'hive';

flush privileges;

再次登录hive

hive> show tables;
OK

能正常的查询表了，希望能帮到有同样问题的人。

================

我的是com.mysql.jdbc.Driver notfound, 所以需要把mysql的驱动放到hive的lib目录
