[jira] Created: (MAPREDUCE-1501) FileInputFormat to support
multi-level/recursive directory listing
FileInputFormat to support multi-level/recursive directory listing
------------------------------------------------------------------
Key: MAPREDUCE-1501
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1501
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Zheng Shao
As we have seen multiple times in the mailing list, users want to have the capability of getting all files out of a multi-level directory structure.
4/1/2008: http://mail-archives.apache.org/mod_mbox/hadoop-core-user/200804.mbox/%3Ce75c02ef0804011433x144813e6x2450da7883de3aca@mail.gmail.com%3E
2/3/2009: http://mail-archives.apache.org/mod_mbox/hadoop-core-user/200902.mbox/%3C7F80089C-3E7F-4330-90BA-6F1C5B0B0F3F@nist.gov%3E
6/2/2009: http://mail-archives.apache.org/mod_mbox/hadoop-common-user/200906.mbox/%3C4A258A16.8050300@darose.net%3E
One solution that our users had is to write a new FileInputFormat, but that means all existing FileInputFormat subclasses need to be changed in order to support this feature.
We can easily provide a JobConf option (which defaults to false) to {{FileInputFormat.listStatus(...)}} to recursively go into directory structure.
