spark-sql报Caused by: java.sql.SQLException: No suitable driver found for jdbc:mysql://xxx:3306

在运行./spark-shell连hive的时候能够运行，但是运行./spark-sql的时候报错如下：

Caused by: java.sql.SQLException: No suitable driver found for jdbc:mysql://hadoop000:3306/hadoop_hive?createDatabaseIfNotExist=true

可能是输入运行命令时没有指定--driver-class-path导致的。

具体说来，在运行./spark-shell的时候，命令是这样的：

[hadoop@hadoop000 bin]$ ./spark-shell --master local[2] --jars ~/software/mysql-connector-java-5.1.27-bin.jar

但在运行./spark-sql时，命令应该加上--driver-class-path，是这样的：

[hadoop@hadoop000 bin]$ ./spark-sql --master local[2] --jars ~/software/mysql-connector-java-5.1.27-bin.jar --driver-class-path ~/software/mysql-connector-java-5.1.27-bin.jar
