问题描述： 我试图sqoop数据，但sqoop返回零记录没有任何错误。 但是当我尝试使用某个限制检索记录时，它会获取数据，但是一旦我继续进行更大限制，它就不会获取任何记录。
The QUERY that was passes using the Sqoop is as mentioned below:
select usr.id,usr.login,usr.auto_login,usr.password,usr.password_salt,usr.member,usr.first_name,usr.middle_name,usr.last_name,usr.user_type,usr.locale,usr.lastactivity_date,usr.lastpwdupdate,usr.generatedpwd,usr.registration_date,usr.email,usr.email_status,usr.receive_email,usr.last_emailed,usr.gender,usr.date_of_birth,usr.securitystatus,usr.description,usr.realm_id,usr.password_kdf,dcspp_order.last_modified_date, 20151223080640 FROM <TABLE_NAME> usr JOIN atgprdcore.dcspp_order ON (usr.id = dcspp_order.profile_id ) WHERE $CONDITIONS'
