Get rid of crc files when using FileUtil.copy(FileSystem srcFS, Path src, File dst, boolean deleteSource, Configuration conf) is used

[Florin P]

Hello!
  We have used the method FileUtil.copy(FileSystem srcFS, Path src, File dst, 
boolean deleteSource, Configuration conf) , and we have seen that some crc 
files were generated for each copied file. We would like that these files do 
not be generated. We have tried to use
FileSystem.setVerifyChecksum(false) but with no effect. We are using hadoop API 
0.20.2-cdh3u1-SNAPSHOT. Can you please help?

Thanks.
