When we copy the files from DFS to local, it is creating the .crc files in local filesystem for the verification of checksum. When user dont want to do any check sum verifications, this files will not be useful.
Command line already has an option ignoreCrc, to control this.
So, we should have the similar option on FileSystem also..... like fs.ignoreCrc().
This should set the setVerifyChecksum to false and also should select the non CheckSumFileSystem as local fs.
