我在单个节点集群上运行hadoop并尝试sqoop将mysql数据导入到hive表中。 问题是在执行sqoop作业时，进程占用的时间和数据不会导入，如下所示：
Sqoop命令：
sqoop job --create Hcustomers -- import --connect jdbc:mysql://localhost/retaildb --username root -P --table customers --check-column id --incremental append --last-value 0 --target-dir '/user/hive/retail/Hcustomers' -m 2;
执行sqoop作业后：
chaithu@localhost:~$ sqoop job --exec Hcustomers;

如上所示，执行卡住了，没有导入数据。附加作业申请的屏幕截图。Sqoop Job Status on Hadoop job tracker
我只想尝试从mysql导入11行到hive，我认为这不应该花费太多时间。可能是什么问题。 请建议我一样。
