我在使用Hue在Oozie中运行sqoop作业时遇到了问题。我有基于Hortonworks HDP的4个节点集群。
我的Sqoop工作如下所示:
import
--options-file ./dss_conn_parms.txt
--table BD.BD_TABLE
--target-dir /user/user_1/DMS
--m 1
--hive-import
--hive-table BD.BD_TABLE_HIVE
Oracle数据库中的数据已成功下载并插入HDFS。不幸的是,Hive导入不起作用。该错误与权限相关:

您是否知道为什么Sqoop作业无法运行Hive导入命令?
更新
我在命令行中使用hive导入选项执行了Sqoop作业,我知道问题是什么。在命令行中,我可以看到这个信息:
Logging initialized using configuration in jar:file:/usr/hdp/2.4.2.0-258 /hive/lib/hive-common-1.2.1000.2.4.2.0-jar!/hive-log4j.properties
OK
问题在于访问位于本地文件系统上的hive-common-1.2.1000.2.4.2.0-jar。知道我该怎么办?
答案 0 :(得分:0)
1)尝试添加
<env-var>HADOOP_USER_NAME=YOUR_USERNAME</env-var>
在workflow.xml中作业定义的<shell xmlns="uri:oozie:shell-action:0.2">
部分
2)在core-site.xml中添加
<property>
<name>hadoop.proxyuser.oozie.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.oozie.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.YOUR_USERNAME.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.YOUR_USERNAME.groups</name>
<value>*</value>
</property>
并重新启动所有服务,然后重试
