[jira] [Created] (KYLIN-3474) get malformed token with Cluster
Mode(multi-query)
Temple Zhou created KYLIN-3474:
----------------------------------
Summary: 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
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?

Hi Zhou
Did you configured Kylin's Cluster Mode correctly? it seems that the cache is not synced.
The key config is to config kylin.server.cluster-servers in kylin.properties.
This properties to tell kylin to sync cache with other servers in the cluster by broadcast.
