_SUCCESS files appearing in demuxOutput

Corbin Hoenes 2011-02-24, 18:12

Anyone seen this?

/chukwa/postProcess/demuxOutputDir_1298061686862/_SUCCESS

I clean them out and I keep getting the same file showing up and chukwa
doesn't know how to handle it:

postProcess.log:

Hi Corbin,

I have not seen this. What is the version of hadoop that you are using, are you using 0.21? It looks like the _SUCCESS file is spill out after demux mapreduce job. There are two possibilities leading to the creation of this file. Demux is modified and it is doing something that is unexpected, or the mapreduce framework 0.21 put that file there.
If you are using 0.21, I would recommend to avoid it.

A more stable version of Hadoop is 0.20.100 branch, and you can download it from:

http://people.apache.org/~eyang/

Eric

This filename is coming from here: http://hadoop.apache.org/mapreduce/docs/r0.21.0/api/constant-values.html
In general for hadoop you may want to avoid looking at any "_*" file since those are Hadoop related files like (_temporary, _log,…)

Re: _SUCCESS files appearing in demuxOutput

We're using Cloudera's CDH3 beta 4 release. Maybe they've patched in the
FileOutputCommitter stuff into their release as it's based on Hadoop 0.20.2
Looking at the source for Chukwa 0.3 (version we are on) the
MoveToRepository class skips the _log and _temporary directories.

Seems like Chukwa should skip the _SUCCESS directory as well? Or could a
more general skip be used like skip anything starting with and underscore?
(maybe too aggressive).

Does Chukwa 0.4 or 0.5 fix this issue? (I'm probably going to just have to
patch 0.3 but maybe just another reason to upgrade.)

Re: _SUCCESS files appearing in demuxOutput

I don't think this has been fixed yet in trunk, let alone 0.4.

I would support skipping everything starting with _. Is there an
actual use case this would break?
