I fixed this issue by downloading the lastest snowflake jar file from this link :  
[https://repo1.maven.org/maven2/net/snowflake/snowflake-jdbc/](https://repo1.maven.org/maven2/net/snowflake/snowflake-jdbc/)

after downloading you need to paste this jar file in you /jars/3rdparty folder and restart snowflake.
