Hi All I think I get the reason. There is a DATE column in my table NMS_CMTS_CPU_CDX_TEST .
And I found the same error on this URL： https://groups.google.com/a/cloudera.org/forum/?fromgroups=#!topic/sqoop-user/I0zqhKOdOyQ According to the URL,I install the Quest Data Connector for Oracle and Hadoop,and It goes well when I export without the DATE column in my table and the corresponding dataset in my HDFS file. On the other hand,When I do the above export job again ,the exception come out. Anyone encountered with the same trouble,or Any suggestion?
