Steve Loughran commented on HADOOP-12426:
-----------------------------------------
finbug check is broken; it's god confused by a \n straight after a %s. Let's
see if inserting a space fixes the confusion
{code}
private String arg(String name, String params, String meaning) {
return String.format("[%s%s%s] : %s\n",
name, (!params.isEmpty() ? " " : ""), params, meaning);
}
{code}

> If we a little command line entry point for testing kerberos settings,
> including some automated diagnostics checks, we could simplify fielding the
> client-side support calls.
> Specifically
> * check JRE for having java crypto extensions at full key length.
> * network checks: do you know your own name?
> * Is the user kinited in?
> * if a tgt is specified, does it exist?
> * are hadoop security options consistent?
