Owen O'Malley resolved HADOOP-5575.
-----------------------------------
Resolution: Cannot Reproduce
This really isn't a bug. Please ask questions over on core-user if you have
questions about how to setup your application.
> regarding output dir usage
> --------------------------
>
> Key: HADOOP-5575
> URL: https://issues.apache.org/jira/browse/HADOOP-5575
> Project: Hadoop Core
> Issue Type: Task
> Environment: ubuntu hardy
> Reporter: girija l
> Fix For: 0.20.0
>
>
> I want to do following:
> 1. A Sequence of map-reduce operations - Found no relevant link / template of
> how it is done.
> 2. An an alternative I thought of passing output/part-00000 file to next
> map-reduce as input file, but then I got the exception for wrong FS while
> accessing output dir. This bug is already fixed in 0.20, but this version I
> am not able to find on apache core - download release page.
> Can anyone help me out with 0.20 distribution?
> Also, if possible can anyone give me an idea of how I can do a sequence of
> map-reduce iterations?
> One more point is - I want my map task to access a common file which ENTIRELY
> should be accessible to it (i.e. not a split one, but the whole file a map
> task should be able to READ) and the same file I want my reducer task to
> write into.
> 2 things:
> 1. how to set such file which won't be split but will be given to each map
> task entirely?
> 2. how can i make all my reducer operating in parallel to modify such file,
> which will be used for next iteration?
> I am not sure whether the things I mentioned above are indeed possible. I am
> new to hadoop..
> Please help,
> Thanks,
