    Okay, I found out for insecure YARN setups (no kerberos auth), I can use something like

    UserGroupInformation ugi = UserGroupInformation.createRemoteUser("vagrant");
    for(Token<? extends TokenIdentifier> toks : UserGroupInformation.getCurrentUser().getTokens()) {
    ugi.addToken(toks);
    }
    ugi.doAs(new PrivilegedAction<Object>() {

    @Override
    public Object run() {
    ...
    });

    ("vagrant" obviously not being hard-coded)

    I'll now investigate the secure case...
