Summary: Errors in WebUI Authentication
Key: KYLIN-2589

Project: Kylin
Issue Type: Bug

Affects Versions: v2.0.0
Environment: EMR
Reporter: Young Wu

There seems bugs exist in the webserver's authentication part in kylin. After
kylin run several hours, user will failed login with username/password. The
error reported in the log is "Encoded password cannot be null or empty".
Detailed attached behind. The only solution is restart kylin timely. Restart
can suppress this issue several hours and then suddenly error comes back again.
ISSUE detail is also here:
http://apache-kylin.74782.x6.nabble.com/Re-Encoded-password-cannot-be-null-or-empty-when-login-into-kylin-s-web-UI-td7879.html#a7887
It is not due to upgrade from 2.0.0-BETA to 2.0.0 since I've already cleaned up
all the info in hbase and spun up a brand new kylin-2.0.0, but the issue is
still there.
Another bug occurs seldom, but it looks like also relates to authentication. It
happens when kylin is having a heavy load of query requests. Details also
attached.
