> I'm trying to fetch back data in Spark SQL using a JDBC connection to Hive.
> Unfortunately, when I try to query data that resides in every column I get

> 1) On Hive create a simple table,its name is "test"，it have three
> column(aname,score,banji),their type both are "String"
> 2)important code:
> object HiveDialect extends JdbcDialect
> { override def canHandle(url: String): Boolean =
> url.startsWith("jdbc:hive2")|| url.contains("hive2")
>
> override def quoteIdentifier(colName: String): String =
> s"`$colName`" }

> JdbcDialects.registerDialect(HiveDialect)
> val props = new Properties()
>
> props.put("driver","org.apache.hive.jdbc.HiveDriver")
> props.put("user","username")
> props.put("password","password")
>
> props.put("fetchsize","20")
> val table=spark.read
> .jdbc("jdbc:hive2://xxxxxxxx:10000","test",props)
