spark 1.4.0 从impala加载数据

[Beyond_H_]

var impala_host = "hadoop-datanode1" //默认使用Hadoop的Datanode1节点连接

def loadDataFromImpala(sqlContext: SQLContext, tableName: String): DataFrame = {

val df = sqlContext.read.format("jdbc").options(Map(
"url" -> s"jdbc:hive2://$impala_host:21050/;auth=noSasl",
"driver" -> "org.apache.hive.jdbc.HiveDriver",
"dbtable" -> tableName)).load()
df
}
spark从1.3.1升级到1.4后,从impala加载数据报错，求解！！

怎么没人回答啊。按照sparkt 最新的1.4版本的API修改后，加载MySQL数据可以，通过impala不行。
