Sqoop 从Hive 导入MySQL 8 提示:org.apache.hadoop.hive.ql.exec.MoveTask. Directory

Posted 2023-03-08 在奋斗的大道

今天使用Sqoop 实现Hive 数据导入mysql 8 提示错误信息如下:

Loading data to table default.hivetomysql
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MoveTask. Directory hdfs://Hadoop3-master:9000/user/hive/warehouse/hivetomysql could not be cleaned up.

造成原因：更新hiveTomysql 表中的数据，我清空了default.hiveTomysql 表记录，但是Hive 元数据存在记录导致从新导入数据失败。

解决办法:删除表重新导入数据
