> 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 the following error:
> Caused by: org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: FAILED: SemanticException [Error 10004]: Line 1:7 Invalid table alias or column reference 'test.aname': (possible column names are: aname, score, banji)

> 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`" }
