Subject [jira] [Commented] (HADOOP-12426) Add Entry point for Kerberos health check
Date Thu, 28 Jan 2016 12:32:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15121343#comment-15121343

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?
