我一遍又一遍地问这个问题,我开始相信我错过了一些非常基本的东西。似乎并没有很多人遇到过这个问题,我真的被困在这个问题上了:
当我在sqoop中使用incrementalmodified指定了merge key参数时,我收到此错误。如果我通过命令行运行该作业,它可以正常工作,但不是当我提交给oozie时。我通过oozie提交工作。不确定oozie是问题还是色调,但sqoop作业不是因为它在通过包括合并步骤在内的命令行执行时确实可以正常工作。
我的sqoop工作如下:
sqoop job --meta-connect jdbc:hsqldb:hsql://FQDN:16000/sqoop
--create test_table -- import --driver com.mysql.jdbc.Driver --connect
jdbc:mysql://IP/DB?zeroDateTimeBehavior=convertToNull --username
USER_NAME --password 'PASSWORD' --table test_table --merge-key id --
split-by id --target-dir LOCATION --incremental lastmodified
--last-value 0 --check-column updated_at
第一次导入正常工作。开始第二次导入:
我创建了一个小的测试表来测试int,datetime和varchar,数据中没有任何NULL或无效的字符,但我遇到了同样的问题:
# id, updated_at, name
'1', '2016-07-02 17:16:53', 'l'
'3', '2016-06-29 14:12:53', 'f'
数据中只有2行,但我得到了这个:

我只在OOZIE中收到此错误,并通过HUE提交作业,当我通过命令行运行sqoop作业时,这可以正常工作包括合并mapreduce
取自oozie启动器,这是我的mapreduce作业日志的样子:
