Caused by: org.datanucleus.exceptions.NucleusException: Attempt to invoke the "BONECP" plugin to create a ConnectionPool gave an error : The specified datastore driver ("com.mysql.jdbc.Driver") was not found in the CLASSPATH. Please check your CLASSPATH specification, and the name of the driver.
缺少mysql的jar包，copy到hive的lib目录下面，OK。

解决办法：修改mysql账号
mysql> update user set user = 'hadoop' where user = 'root' and host='%';
Query OK, 1 row affected (0.04 sec)

解决，去远程mysql库上修改字符集从utf8mb4修改成utf8
mysql> alter database hive_remote /*!40100 DEFAULT CHARACTER SET utf8 */;
Query OK, 1 row affected (0.03 sec)
mysql>
然后在data01上面配置hive client端
scp -r hive-0.13.1/ data01:/home/hadoop/src/

继续启动，查看日志信息：
[hadoop@name01 conf]$ hive --service metastore

卡在这里不动，去看日志信息
