>
> The ClientRMSerivce doesn't allow delegation token owners to cancel their own
> tokens. The root cause is this piece of code from the cancelDelegationToken
> function -
> {noformat}
> String user = getRenewerForToken(token);
> ...
> private String getRenewerForToken(Token<RMDelegationTokenIdentifier> token)
> throws IOException {
> UserGroupInformation user = UserGroupInformation.getCurrentUser();
> UserGroupInformation loginUser = UserGroupInformation.getLoginUser();
> // we can always renew our own tokens
> return loginUser.getUserName().equals(user.getUserName())
> ? token.decodeIdentifier().getRenewer().toString()
> : user.getShortUserName();
> }
> {noformat}
> It ends up passing the user short name to the cancelToken function whereas
> AbstractDelegationTokenSecretManager::cancelToken expects the full user name.
> This bug occurs in secure mode and is not an issue with simple auth.
