When your code does a listStatus, you can pass a PathFilter object
along that can do this filtering for you. See
http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/fs/FileSystem.html#listStatus(org.apache.hadoop.fs.Path,%20org.apache.hadoop.fs.PathFilter)

I got the problem with I am unable to solve it. I need to apply a filter
for _SUCCESS file while using FileSystem.listStatus method. Can someone
please guide me how to filter _SUCCESS files. Thanks

problem occurs when run it under hadoop 1.0.3.

But the thing is, it works with hadoop 0.20. even with 100 x100(and even

Not found the same issue when testing with writing fairly small files ( <
1GB).

Hi,
If you are using a custom writable object while passing data from the
mapper to the reducer make sure that the read fields and the write has the
same number of variables. It might be possible that you wrote datavtova
file using custom writable but later modified the custom writable (like

Waqas,
Can you ensure this file isn't empty (0 in size)?

Regards, waqas. I think that you have to ask to MapR experts.
