----------------------------------------
Summary: Metadata Caching + Impersonation : Inconsistency in
reporting a permission error
Key: DRILL-3828
URL: https://issues.apache.org/jira/browse/DRILL-3828
Project: Apache Drill
Issue Type: Bug
Components: Metadata
Reporter: Rahul Challapalli
Assignee: Mehant Baid
git.commit.id.abbrev=3c89b30
User A has permissions to lineitem and lineitem/2006. He does not have access
to lineitem/2007
Scenario 1 : There is already a cache file created by a different user in the
lineitem folder, then
a) refresh table metadata lineitem : succeeds
b) refresh table metadata `lineitem/2007` : fails with a permission error
Scenario 2 : There is no cache file in the lineitem folder, then
a) refresh table metadata lineitem : fails with permission error
b) refresh table metadata `lineitem/2007` : fails with a permission error
Scenario 2 seems to be the expected result in this case as the cache file
contains metadata information about file from within the sub-directories as well
