Updated file for DistributedCache

[#1]

I have one file that I load into DistributedCache. Then I run my mapreduce program. After completion of the job, I want to update my file. DistributedCache will automaticli download new version of the file, when I run my program with the same parameters?

Yes, distributed cache will update the file if it has changed (timestamp or length).
