> For azure hdinsight we need to change node manager to run as virtual account instead of use account. Else after azure reimage, it wont be able to access the map output data of the running job in that node. But when we changed the nodemanager to run as virtual account we got this error,

> Fix - When node manager runs as virtual account, the resourcelocalization service fails to come. It checks for the permission of usercache and file cache to be 755 and nmPrivate to be 700. But in windows, for virtual account, the owner and group is same. So this pemrission check fails. So added a check that is user is equal to group, then umask validation dont hold
