下面的代码是使用spark从配置单元表读取数据。这个表有一亿条记录。当我在rdd中选择这么多记录并尝试执行result.show()时,会出现严重的问题异常。
我基本上想通过从这个表中为1亿个记录集选择几列来在其他表中插入记录。
这是我的密码:
import org.apache.spark.sql.functions._
import org.apache.spark.sql._
val sqlContext = new org.apache.spark.sql.SQLContext(sc)
val hiveContext = new org.apache.spark.sql.hive.HiveContext(sc)
val result=sqlContext.sql("Select * from******reception.recp_customer")
result: org.apache.spark.sql.DataFrame = [data_source_id: smallint, customer_bkey: string ... 129 more fields]
result.show()
java.lang.RuntimeException: serious problem

不知道是什么导致了这种情况。我知道数据集是巨大的如何处理它。

看起来像你的
hive
表是一个ACID
table。为了acid
只能使用的表格hive
要进行查询,不能使用spark
无法查询它们,因为spark尚不支持此功能。你可以按照下面的步骤来做

行:caused by:java.lang.numberformatexception:for input string:“0000312\u 0000”表示您正试图使用字符串值,因为它是数字。过来看。
