The error tolerance of Sqoop itself depends on Hadoop. Here we focus on the processing of Sqoop transmission task failure. Specifically, how does the focus solve the data consistency problem caused by the failure of the transmission task in Sqoop? For A transfer task, data is transmitted from A to B. If the transfer task fails, the statuses of A and B should be c
