-------------------------------------
Could be related means that you need session persistence in the LB?
> get malformed token with Cluster Mode(multi-query)
> --------------------------------------------------

> Key: KYLIN-3474
> 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 the 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?
