Subject [jira] [Commented] (MAPREDUCE-3193) FileInputFormat doesn't read files recursively in the input path dir
Date Thu, 19 Apr 2012 07:21:48 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13257331#comment-13257331

Shilo Ayalon commented on MAPREDUCE-3193:

I'm having the same problem with hadoop-1.0.2. Given the following directory structure (in

├── three/
│   └── four/
│       ├── baz.txt
│       ├── bleh.txt
│       └── foo.txt
└── two/
    ├── bar.txt
    └── gaa.txt

As no recursive path support is available, I'm walking the root folder and adding all subdirs
to the job. However, adding file-less folders like {{one}} and {{one/three}} as input paths
to the job raises this exception:
java.io.FileNotFoundException: /user/hduser/data/one (Is a directory)

The actual number of files present is massive (20k/30k+), so passing all on the command line
seems redundant. Will this patch be added to the source at some point?
