pyspark can't access mariadb via jdbc

I want to access mariadb using pyspark but error raised.
my notebook as follows.

```bash
%spark.dep
z.load("/zeppelin/interpreter/jdbc/mariadb-java-client-2.2.0.jar")
->
res0: org.apache.zeppelin.dep.Dependency = org.apache.zeppelin.dep.Dependency@6ed2e421
```

```bash
%spark.pyspark
import pyspark
print(pyspark._version_)

dataframe = sqlContext.read.format("jdbc").options(
url ="jdbc:mariadb://mariadb:3306/db",
driver="org.mariadb.jdbc.Driver",
dbtable="table",
user="user",
password="pass"
).load().take(10)

->
2.1.0
