Description

Bug in the substitution code in authorization.cc:

if (status.ok()) {
  stringstream ss;
  ss << "InitKerberos call to gethostname failed: errno " << errno;
  LOG(ERROR) << ss;
  return Status(ss.str());
}
FLAGS_principal.replace(off, HOSTNAME_PATTERN.size(), hostname);

The result is that Impala exits if --principal contains _HOST which is not right.
