Hitesh Shah commented on TEZ-1879:
----------------------------------
Clarification:
With the change, there is now:
{code}
+ this.appMasterUgi = UserGroupInformation
+ .createRemoteUser(jobUserName);
{code}
Earlier, in local mode:
appMasterUgi = UserGroupInformation.getCurrentUser();
Will this create any issues in local mode?
> Create local UGI instances for each task and the AM, when running in LocalMode
