Na Li updated SENTRY-2091:
--------------------------
Status: Patch Available (was: Open)
> User-based Privilege is broken by SENTRY-769
> --------------------------------------------
>
> Key: SENTRY-2091
> URL: https://issues.apache.org/jira/browse/SENTRY-2091
> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 2.1.0
> Reporter: Na Li

>
> SENTRY-769 throws exception when a user has no group. This breaks user-based
> privilege as the exception prevents getting privilege using user-based
> privilege.
> For example, in the following code
> {code}
> Set<String> userPrivileges =
> authProvider.getPolicyEngine().getPrivileges(
> authProvider.getGroupMapping().getGroups(userName),
> Sets.newHashSet(userName),
> hiveAuthzBinding.getActiveRoleSet(),
> hiveAuthzBinding.getAuthServer());
> {code}
> when user has no group, the exception causes the processing stops even when
> user has privilege.
> The solution is to catch the exception, and continue the processing.
> {code}
> try {
> Set<String> groups = null;
> try {
> groups = authProvider.getGroupMapping().getGroups(userName)
> } catch (SentryGroupNotFoundException ex) {
> log.debug(...);
> groups = new HashSet<String>();
> }
> Set<String> userPrivileges =
> authProvider.getPolicyEngine().getPrivileges(
> groups, Sets.newHashSet(userName),
> hiveAuthzBinding.getActiveRoleSet(),
> hiveAuthzBinding.getAuthServer());
> ...
> }
> {code}
