我正在尝试使用hadoop sqoop从presto数据库中摄取数据,这会在presto中引发以下错误:

18/07/12 10:34:05 DEBUG manager.SqlManager: No connection paramenters specified. Using regular API for making connection.
18/07/12 10:34:06 ERROR manager.SqlManager: Error executing statement: java.sql.SQLException: [Teradata][Presto](100050) Query failed: Current transaction is aborted, commands ignored until end of transaction block.

因为presto db侧没有错误。sqoop命令:

sqoop-import \
--verbose \
--driver com.teradata.presto.jdbc42.Driver
--connect 'jdbc:presto://bla:8443/hive?SSL=true&SSLTrustStorePath=bla&SSLTrustStorePassword=bla' \
--username bla -P \
--table hive.bla.blah \
--m 2

teradata presto驱动程序版本:prestojdbc42-1.0.21.1031.jar

配置单元连接器仅支持read\u uncommitted,而sqoop似乎正在请求read\u committed,这是不受支持的。如果可以将sqoop改为uncommitted,那么它应该可以工作。
