-------------------------------------------
Summary: If we change node manager identity to run as virtual
account, then resource localization service fails to start with incorrect
permission
Key: YARN-3962
URL: https://issues.apache.org/jira/browse/YARN-3962
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.7.1
Reporter: madhumita chakraborty
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
