为什么我无法使用apache spark连接到配置单元metastore？

Question

我正尝试使用apache的火花与java程序的帮助连接的Apache配置单元。下面是程序：

import org.apache.spark.sql.SparkSession; 

public class queryhive { 

    public static void main(String[] args) 
{ 
    String warehouseLocation = "spark-warehouse"; 

    SparkSession spark = SparkSession 
      .builder() 
      .appName("Java Spark Hive Example") 
      .master("local[*]") 
      .config("spark.sql.warehouse.dir", warehouseLocation) 
      .enableHiveSupport() 
      .getOrCreate(); 
try 
{ 
     spark.sql("select count(*) from heath1").show(); 
} 
catch (Exception AnalysisException) 
{ 
    System.out.print("\nTable is not found\n"); 
} 
} 
} 

我已经加入到maven的pom.xml中：HDFS的地址和蜂巢在<properties>标签的地址。
我想查询使用spark的配置单元表。但我看不到表，因为我得到表外未发现：

我使用Apache蜂巢1.2.0和2.1.0星火
我相信这个问题是因为版本的不。使用Eclipse Neon作为IDE.Kindly，让我知道为什么我面临这个问题以及我如何解决它。

Answer 1

您需要指定模式名称。无论是作为SELECT * FROM schmaName.tableName或如下所示

try 
{ 
     spark.sql("use schemaName")   // name of the schema 
     spark.sql("select count(*) from heath1").show(); 
} 
catch (Exception AnalysisException) 
{ 
    System.out.print("\nTable is not found\n"); 
}
