Hi all
My cluster env is:
Ubuntu server 20.4
Hadoop3.3.2
Hive3.1.2
Hbase2.4.11
Spark3.2.1
mysql  Ver 8.0.29-0ubuntu0.20.04.3 for Linux on x86_64

My kylin version is:  kylin-4.0.1-bin-spark3.tar.gz

I created user kylin in mysql and create databases both kylin and 
kylin_metastore

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| hive_metastore     |
| information_schema |
| kylin              |
| kylin_metastore    |
| mysql              |
| performance_schema |
| sys                |
+--------------------+
7 rows in set (0.00 sec)

I created ext fold:
michael@hadoop-cluster-001:~/opt/modules/kylin/apache-kylin-4.0.1-bin-spark3$ 
ls ext/
mysql-connector-java.jar

And I also set kylin.metadata.url in conf/kylin.properties:
kylin.metadata.url=kylin_metadata@jdbc,url=jdbc:mysql://hostname:3306/kylin,username=kylin,password=kylin,maxActive=10,maxIdle=10

But when I start kylin, I got error below:

How can I solve this problem? Thanks!
