场景：

关键信息No column is found to partition data查了资料没发现什么意思，后来细想，greenplum在环境中都是有分部键的
然后我对我的sqoop  job做了update

有如下信息
Schema name: datamart
Table name:table_name
Table SQL statement:
Table column names:
Partition column name:
Null value allowed for the partition column:
Boundary query:

Partition column name分区的列名，正好我把表table_name的分布键加了上去，然后start job --jid 1
执行成功
