Sorabh Hamirwasia created DRILL-5704:
----------------------------------------
Summary: Improve error message on client side when queries fail
with "Failed to create schema tree." when Impersonation is enabled and logins
are anonymous
Key: DRILL-5704
URL: https://issues.apache.org/jira/browse/DRILL-5704
Project: Apache Drill
Issue Type: Improvement
Reporter: Sorabh Hamirwasia
When username is not specified then Drill set's the session user as anonymous
if impersonation is enabled. During query execution Drill tries to build schema
tree and as part of that it validates if the user has access to the workspace
or not by using FileClient Api liststatus which verifies the user from the OS
user. Since impersonation is only enabled here without authentication and we
don't specify any user in connection string, Drill will use default user which
is "anonymous" and pass that to check workspace permission which will fail as
node doesn't have any valid user with that name.
