Question

将表从SQLServer导入Hive时，我面临以下异常

/tmp/sqoop-hduser/compile/a6db7754847c4d49c9164758fcc079d7/ReceivedData.java:513:      error: incompatible types
this.IDReceivedData = Long.valueOf(__dataIn.readLong());
required: Long
found:    Double

                                    ^

以下是用于导入表格的命令

特定列（IDReceivedData）的数据类型是数据库中的BigInt。这可能是什么问题？我是否必须更改数据库中列的数据类型？或使用sqoop import命令进行任何其他更改。

sqoop import --connect "jdbc:sqlserver://<ip>:1433;database=temp;user=sa;password=pass" --table ReceivedData --hive-table temp.ReceivedData

任何帮助都将不胜感激。

谢谢，卡莱

Sqoop目前不支持BigInteger，对于解决方法，您可以将特定列映射为字符串

--map-column-java IDReceivedData=String

使用BigInt数据类型导致Sqoop导入错误
