UCSD Hadoop User and Account Mappings

This twiki is for decribing the UCSD CMS T2 Hadoop and GUMS account mappings to support the CMS experiments storage account requirements.

The overall objective in CMS is to have multiple types of privileges:

  • general users that are supported by our site in /store/user
  • groups assigned to our site, and within those groups 2-3 specially privileged user that have access to the role priorityuser.
  • dataOps for producing MC
  • phedex

All of these come with special write privileges, and all except PhEDEx? also come with special CPU access privileges. On this twiki we describe only the write access arrangement.
