我已经成功安装了hive和mysql，我按照link中的建议对hive进行了配置。但我看到一个错误如下：
Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
..
..
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.所以我在hive的lib中添加了mysql-connector-java.jar。现在Hive挂起来了，我一点也没拿到壳。
请建议我如何解决它
