Spark 1.4连接mysql诡异的问题及解决

在spark-default.conf文件中明明配置了mysql的数据源连接

随后启动spark-shell 执行如下测试代码：

import org.apache.spark.{SparkContext, SparkConf}
import org.apache.spark.sql.{SaveMode, DataFrame}
import org.apache.spark.sql.hive.HiveContext

val mySQLUrl = "jdbc:mysql://localhost:3306/yangsy?user=root&password=yangsiyi"

  val people_DDL = s"""
            CREATE TEMPORARY TABLE PEOPLE
            USING org.apache.spark.sql.jdbc
            OPTIONS (
              url    '${mySQLUrl}',
              dbtable     'person'
            )""".stripMargin

    sqlContext.sql(people_DDL)
    val person = sql("SELECT * FROM PEOPLE").cache()

val name = "name"
val targets = person.filter("name ="+name).collect()

collect()的时候报找不到driver

这个问题就很诡异了。。数据源连接也没错啊，毕竟在hive的metastore也是用的这个啊。。最终只能在启动spark-shell的时候同时引入jar包了= =

./spark-shell --jars /usr/local/spark-1.4.0-bin-2.5.0-cdh5.2.1/lib/mysql-connector-java-5.1.30-bin.jar

随后再执行就OK了。。诡异。。

或者在执行collect()之前引入mysql的jar包也可以

sqlContext.sql("add jar /usr/local/spark-1.4.0-bin-2.5.0-cdh5.2.1/lib/mysql-connector-java-5.1.30-bin.jar")

不过总感觉不妥。。有解决办法的求指导哈~
