hive启动出问题

Question

Nested Throwables StackTrace:java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://192.168.1.148:3306/hive?createDatabaseIfNotExist=true, username = hadoop. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failureThe last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)    at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)。。。Hadoop装好了，没问题，mysql也装了，也没出现问题，装了hive后在命令行输入hive就这样了，困在这个地方整整一天了，求教！
