-------------------------------------
Summary: DAGAppMaster should access resources in UGI context on
startup
Key: TEZ-4024
URL: https://issues.apache.org/jira/browse/TEZ-4024
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.9.1
Reporter: Eric Wohlstadter
Assignee: Eric Wohlstadter
On startup, DAGAppMaster accesses resources such as config PBs and staging dirs
as yarn rather than through the UGI context.
This creates access control violations when yarn does not have permissions for
those resources.
This also seems odd, since during shutdown, DAGAppMaster does access resources
through UGI.
