Hi Florin, Recently i had given the patch for controlling .crc files at client side. Please look at https://issues.apache.org/jira/browse/HADOOP-7178.
Provided one extra API in FileSystem.java, public void copyToLocalFile(boolean delSrc, Path src, Path dst, boolean useRawLocalFileSystem) If you pass useRawLocalFileSystem as true, then .crc files will not be created. By default copy APIs will use LocalFileSystem.java as local, LocalFileSystem is extends the CRCFileSysstem. so , we will get crc files at local. FileSystem.setVerifyChecksum(false) is only for not verify the checksums. It will not control the .crc file creations.
