> In UserGroupInformation, getGroupNames() swallows the original exception. There have been many occasions that more information on the original exception could have helped.
> {code}
> public synchronized String[] getGroupNames() {
> ensureInitialized();
> try {
> List<String> result = groups.getGroups(getShortUserName());
> return result.toArray(new String[result.size()]);
> } catch (IOException ie) {
> LOG.warn("No groups available for user " + getShortUserName());
> return new String[0];
> }
> }
> {code}
