madhumita chakraborty updated YARN-3962:
----------------------------------------
    Attachment: Yarn-3962.001.patch

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

> If we change node manager identity to run as virtual account, then resource 
> localization service fails to start with incorrect permission

> 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,
