我正在尝试在色调中运行mapreduce作业。我按照以下步骤操作:
Fill out the Edit Node form
1)Enter ooziemrwf as the name, and "oozie MapReduce workflow" as the description.
2) Navigate to the JAR file location and upload the JAR file.
3) Click the Add Property button and add each of these four properties:
Property Name
Value
mapred.mapper.class org.apache.oozie.example.SampleMapper
mapred.reducer.class org.apache.oozie.example.SampleReducer
mapred.output.dir /user/mapr/mapreducejob/wfoutput
mapred.input.dir /oozie/examples/input-data/text
4) Navigate to the JAR file and select it as the input path.
5)Click Done. The MapReduce action appears in the workflow.
6) Click Save.
Under Actions in the navigation panel, click Submit. When the Submit this job? dialog appears, click Submit.
我上传了工作jar添加的属性,我无法理解第4步ieNavigate到JAR文件并选择它作为输入路径。有人可以告诉那究竟是什么?你可以参考http://doc.mapr.com/display/MapR/Working+with+Hue

此时不确定您是否能够“运行”任何内容。 有很多事情可能会出错。
我假设你正在使用HUE来创建Job Def。
