-------------------------------------

Could be related means that you need session persistence in the LB?

>                 URL: https://issues.apache.org/jira/browse/KYLIN-3474
>             Project: Kylin
>          Issue Type: Bug
>          Components: Query Engine, Security
>    Affects Versions: v2.4.0
>            Reporter: Temple Zhou
>            Priority: Major

> I found that when I use Tableau 10.5 with Kylin 2.4.0(multi-query) , the Tableau Server
will get theĀ malformed token error when do query via restful API.
> However, when I use Tableau 10.5 with Kylin 2.4.0(single query instance), the error will
be gone.
> Now, I just annotate the following lines(org.apache.kylin.rest.security.KylinAuthenticationProvider
84-87) and the Tableau 10.5 can run regularly with Kylin 2.4.0(multi-query).
> {code:java}
>  @Override
>     public Authentication authenticate(Authentication authentication) throws AuthenticationException
{
>         byte[] hashKey = hf.hashString(authentication.getName() + authentication.getCredentials()).asBytes();
>         String userKey = Arrays.toString(hashKey);
>         // if (userService.isEvictCacheFlag()) {
>         //     userCache.invalidateAll();
>         //     userService.setEvictCacheFlag(false);
>         // }
>         Authentication authed = userCache.getIfPresent(userKey);
>         if (null != authed) {
>             SecurityContextHolder.getContext().setAuthentication(authed);
>         } else {
> {code}
> I don't know if you tested the Kylin(multi-query) Cluster Mode with Tableau?
