启动指定的job: 该job执行完后查看HDFS上的文件(hdfs fs -ls hdfs://dtbigdata1:9000/tmp/data/)
start job --jid 2
查看指定job的执行状态:
status job --jid 2
停止指定的job:
stop job --jid 2
在start job(如：start job --jid 2)时常见错误：
Exception has occurred during processing command
Exception: org.apache.sqoop.common.SqoopException Message: CLIENT_0001:Server has returned exception
在sqoop客户端设置查看job详情：
set option --name verbose --value true
show job --jid 2
