---------------------------------------------
Hi Nicholas,
Thanks alot for taking a look on this issue.
If you suggest to add API, i am open for that! :-)
reason Why i added ignoreCrc api is, commandline already has the option to
specify ignoreCrc. Just to make it sync i proposed ignoreCrc in FileSystem also.
your idea also good. I will update the patch.
--Thanks
> FileSystem should have an option to control the .crc file creations at Local.

> 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.
