> The below testing has been done with impersonation enabled
> User A has 755 permissions on the 'lineitem' folder and does not have read access to the subfolder 'lineitem/2006'. The below query rightly fails
> {code}
> select count(*) from dfs.`/drill/testdata/metadata_caching/lineitem`;
> Error: PERMISSION ERROR: Not authorized to read table [/drill/testdata/metadata_caching/lineitem] in schema [dfs.default]
> [Error Id: c3238ee0-4338-46bf-ba7c-875d995d62d0 on qa-node190.qa.lab:31010] (state=,code=0)
> {code}
> Now some other user who has access to 'lineitem' and its sub-folders ran the 'refresh table metadata" command.
> Now user A executes the above same query and gets the result back skipping the security checks
> {code}
> select count(*) from  dfs.`/drill/testdata/metadata_caching/lineitem`;
