      Description

      In UserGroupInformation, getGroupNames() swallows the original exception. There have been many occasions that more information on the original exception could have helped.

        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];
          }
        }
