Hadoop MapReduce provide nested directories as job input

Question

I\'m working on a job that processes a nested directory structure, containing files on multiple levels:

one/
├── three/
│   └── four/
│       ├── baz.txt
│               


        

Answer 1

import org.apache.hadoop.mapreduce.lib.input.FileInputFormat;

FileInputFormat.setInputDirRecursive(job, true);

No thanks, just call me LeiFeng!
