Description

As ServiceClient uses UserGroupInformation.getCurrentUser().getUserName() to get user whereas ClientRMService#submitApplication uses UserGroupInformation.getCurrentUser().getShortUserName() to set application username.
In case of user with name hdfs/[e-mail]. below condition fails
ClientRMService#getApplications()

if (users != null && !users.isEmpty() &&
          !users.contains(application.getUser())) {
        continue;
 }
