这篇文章给大家介绍sqoop中query \$CONDITIONS HUE执行失败怎么办,内容非常详细,感兴趣的小伙伴们可以参考借鉴,希望对大家能有所帮助。
1. HUE sqoop命令框中直接输入:
sqoop-import --connect jdbc:mysql://ip地址:端口/数据库 --username 用户名 --password 密码 --query select * from 表名 where 1=1 and \$CONDITIONS --split-by id --hive-table hive表 --target-dir /apps/hive/warehouse/mydb.db/product/dt=${date} --hive-partition-key dt --hive-partition-value ${date} --hive-import --driver com.mysql.jdbc.Driver
运行会提示报错,是因为SQL语句被解析成sqoop参数
2784 [main] ERROR org.apache.sqoop.tool.BaseSqoopTool - Error parsing arguments for import:
2016-09-11 15:21:46,485 ERROR [main] tool.BaseSqoopTool (BaseSqoopTool.java:hasUnrecognizedArgs(304)) - Error parsing arguments for import:

2785 [main] ERROR org.apache.sqoop.tool.BaseSqoopTool - Unrecognized argument: where
2016-09-11 15:21:46,486 ERROR [main] tool.BaseSqoopTool (BaseSqoopTool.java:hasUnrecognizedArgs(307)) - Unrecognized argument: where
2785 [main] ERROR org.apache.sqoop.tool.BaseSqoopTool - Unrecognized argument: $CONDITIONS
2. 解决方案: 最好采用参数化的方式
<workflow-app name="test" xmlns="uri:oozie:workflow:0.5">
<start to="sqoop-fb61"/>
<kill name="Kill">
<message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<action name="sqoop-fb61">
<sqoop xmlns="uri:oozie:sqoop-action:0.2">
