Knox problem with NullPointerException

Hi everyone~

I am installing Knox and facing some null pointer exception when testing beeline using jdbc or testing Yarn Examples via cURL.
There first show HTTP 500, and then I found some null exception in knox log.
ps. Knox for WebHDFS is work fine by the way.

This is my jdbc Connection :
!connect jdbc:hive2://hdpgateway1.local:8443/;ssl=true;sslTrustStore=/etc/knox/knox-0.4.0/data/security/keystores/gateway.jks;trustStorePassword=passwd?hive.server2.transport.mode=http;hive.server2.thrift.http.path=gateway/hdp/hive william william-passwd
This is my testing yarn via cURL:
curl -ikv -u william:william-passwd -X GET 'https://hdpgateway1.local:8443/gateway/hdp/resourcemanager/v1/cluster'

I think I must missing something. Thanks in advance.

Here is the null exception message from gateway.log

INFO  hadoop.gateway (KnoxLdapRealm.java:getUserDn(479)) - Computed userDn: uid=william,ou=people,dc=test,dc=com using dnTemplate for principal: william
