英文:
how to set dummy variable as path in multipleinput in map-reduce
问题
我已经使用`scan`将HBase表数据传递给了Mapper。是否有办法在`MultipleInput()`中将虚拟路径或变量设置为路径参数？
List<Scan> scans = new ArrayList();
scans.add(data);
TableMapReduceUtils.initTableMapperJob(scans, Mapper.class,
ImmutalbeWriteable.class, ImmutalbeWriteable.class, job);
MultipleInputs.addInputPath(job, new Path("DUMMY"),
SequenceFileInputFormat.class, Mapper.class)
> 当我像这样在路径中传递`DUMMY`变量时，我遇到了错误：此路径不存在。

I have passed hbase table data using scan to the mapper. Is there any way to set Dummy path or variable as path argument in MultipleInput()

ImmutalbeWriteable.class, ImmutalbeWriteable.class, job);
MultipleInputs.addInputPath(job, new Path("DUMMY"),
