broken gzip file

[Vadim Zaliva]

I have a bunch of gzip files which I am trying to process with Hadoop  
task. The task fails with exception:
java.io.EOFException: Unexpected end of ZLIB input stream at

I guess some of files are invalid. However I could not find anywhere  
in logs file name of the file causing this exception. Due to the huge  
size of the dataset I would not want to extract files from DFS and  
verify them with Gzip one by one. Any suggestions? Thanks!
Sincerely,
Vadim
