> Currently AbstractDelegationTokenSecretM anager$checkToken does
> {code}
>   protected DelegationTokenInformation checkToken(TokenIdent identifier)
>       throws InvalidToken {
>     assert Thread.holdsLock(this);
>     DelegationTokenInformation info = getTokenInfo(identifier);
>     if (info == null) {
>       throw new InvalidToken("token (" + identifier.toString()
>           + ") can't be found in cache");
>     }
>     if (info.getRenewDate() < Time.now()) {
>       throw new InvalidToken("token (" + identifier.toString() + ") is 
> expired");
>     }
>     return info;
>   } 
> {code}
> When a token is expried, we throw the above exception without printing out 
> the {{info.getRenewDate()}} in the message. If we print it out, we could know 
> for how long the token has not been renewed. This will help us investigate 
> certain issues.
> Create this jira as a request to add that part.
