我正在尝试将df写入hive:
df_block_identity.printSchema()

遵循此架构的示例数据:
AHA d4cd8d01-6a4f-446c-838e-ded98c1e8d53 TOTO TOTO NULL . xxx@gmail.com NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL [{"publicID_Services":"d4cd8d01-6a4f-446c-838e-ded98c1e8d53","CreationAppSource_Services":"TOTO","LastUpdateAppSource_Services":"TOTO","ServiceTypeId":"OPTINS","ServiceId":"PARTENAIRES","ServiceStatus":true,"ActivationDate":"2015-09-18 00:00:00","DeactivationDate":"9999-12-31 23:59:59.999"},{"publicID_Services":"d4cd8d01-6a4f-446c-838e-ded98c1e8d53","CreationAppSource_Services":"TOTO","LastUpdateAppSource_Services":"TOTO","ServiceTypeId":"OPTINS","ServiceId":"NEWSLETTER","ServiceStatus":true,"ActivationDate":"2015-09-18 00:00:00","DeactivationDate":"9999-12-31 23:59:59.999"}] NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL NULL
我使用命令: df_block_identity.write.saveAsTable('sb_party_hub_dev.golden', mode='overwrite', format="parquet")
此命令完成正常。我可以看到Hive元商店里的table。
但是当你试图从Hive里请求 select * from sb_party_hub_dev.golden
,我收到错误:
java.io.ioexception:org.apache.parquet.io.parquetdecodingexception:无法读取文件中块-1中0处的值adl://home/hive/warehouse/sb_party_hub_dev.db/golden/part-r-00000-e3dcac27-021e-43e8-8687-01ae305d5b5d.snappy.parquet
当我删除字段时 service
是数组类型 select
检索表的内容。
我应该在pyspark代码中更改什么,以便在配置单元中编写表并能够无错误地查询它?
编辑:
我尝试了另一种格式: df_block_identity.write.saveAsTable('sb_party_hub_dev.golden', mode='overwrite', format="orc")
使用这种格式,我可以通过配置单元访问数据。为什么Parquet地板会失效呢?
