----------------------------------------
Summary: CompositeGroupsMapping should not swallow exceptions
Key: HADOOP-14743
URL: https://issues.apache.org/jira/browse/HADOOP-14743
Project: Hadoop Common
Issue Type: Bug
Reporter: Wei-Chiu Chuang
Assignee: Wei-Chiu Chuang
{code:title=CompositeGroupsMapping#getGroups}
for (GroupMappingServiceProvider provider : providersList) {
try {
groups = provider.getGroups(user);
} catch (Exception e) {
//LOG.warn("Exception trying to get groups for user " + user, e);
}
if (groups != null && ! groups.isEmpty()) {
groupSet.addAll(groups);
if (!combined) break;
}
}
{code}
If anything fails inside the underlying groups mapping service provider,
there's no way to tell what went wrong.
