当我使用sqoop export命令将数据从配置单元导出到mirosoft sql server时,在ambary视图中使用sqoop actin和hcatalog时出现问题。
下面的命令在shell中正确运行,效果非常好。
sqoop export --connect 'jdbc:sqlserver://x.x.x.x:1433;useNTLMv2=true;databasename=BigDataDB' --connection-manager org.apache.sqoop.manager.SQLServerManager --username 'DataApp' --password 'D@t@User' --table tr1 --hcatalog-database temporary --catalog-table 'daily_tr'
但是,当我在oozie工作流中使用此命令创建sqoop操作时,出现以下错误:

为解决此错误,我执行以下操作:
在workflow.xml所在的文件夹下,我创建文件夹lib并将sharedlibdir(/user/oozie/share/lib/lib_/hive)中的所有配置单元jar文件放在那里
我的目标是做到这一点,组件识别hcatalogjar文件和类路径,所以我不确定这一点,也许我不应该这样做,并为这个错误提供不同的解决方案
无论如何,执行此操作后,错误已更改如下:

请帮助我解决错误和问题,为什么sqoop命令在shell中正常工作,而在oozie工作流中却有错误?

我通过以下方法解决了我的问题:
1-在workflow.xml中的命令标记中使用(--hcatalog home/usr/hdp/current/hive webhcat):
2-在hdfs上,在workflow.xml旁边创建lib文件夹,并将hive-site.xml和tez-site.xml放到其中(从/etc/hive/2.6.5.0-292/0/上传hive-site.xml,从/etc/tez/2.6.5.0-292/0/上传tez-site.xml到hdfs上的lib文件夹)
根据上面在工作流中定义的两个文件(hive-site.xml和tez-site.xml)
3-在job.properties文件中定义以下属性:
4-确保/etc/oozie/conf下的oozie-site.xml指定了以下属性。

我不知道这是不是罪魁祸首。一年前我在hdp中用sqoop1.4.x面对这个问题,它显示了一些无关的失败原因。
当您从命令行运行低于sqoop命令时,它将成功运行。
但是当您通过ooziesqoop操作运行同一个命令时,它不应该像下面那样有单引号(')。
