mysql connect string
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;

| 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!

Hi,
1. As example, my metadata url is "kylin.metadata.url=kylin_test@jdbc,url=jdbc:mysql://localhost:3306/kylin,username=root,password=xxxx,maxActive=10,maxIdle=10", and please make sure that your "hostname" is a correct host to the DB! Not the string "hostname" only.
2. what is the version of mysql-connector-java.jar? As a normal jar of the connector, I use the jar "mysql-connector-java-5.1.40.jar".
