【问题描述】：

当我将数据加载到表格时出现错误，感谢您的帮助。

hive> load data local inpath '/home/Xperttech/Desktop/datagen_10.txt' into table patient;

Copying data from file:/home/Xperttech/Desktop/datagen_10.txt
Copying file: file:/home/Xperttech/Desktop/datagen_10.txt
Loading data to table default.patient
Failed with exception Unable to alter table.
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.MoveTask

但是数据会正常插入。

只有当我使用 mysql 进行元存储时才会发生这种情况。当我换回德比时，一切正常。我确定mysql运行良好，从hive登录成功。
