Hi, Getting below error while running the logstash pipe line with ing-bank cassandra jdbc driver. ```auto [ERROR] 2024-05-14 05:16:54.776 [Converge PipelineAction::Create

What do the jdbc\_driver\_class and associated options look like on the jdbc input? ---

I have passed `com.ing.data.cassandra.jdbc.CassandraDriver` as per driver class documentation. `(https://github.com/ing-bank/cassandra-jdbc-wrapper)` ---

Read the notes related to jdbc\_driver\_class and jdbc\_driver\_library in the [documentation](https://www.elastic.co/guide/en/logstash/8.13/plugins-inputs-jdbc.html#plugins-inputs-jdbc-jdbc_driver_class). Decide whether it should be loading through jdbc\_driver\_library or the JVM classpath. Are the permissions correct? Is the name correct (see documentation again)? ---

I have passed both lib and driver class information. ````jdbc jdbc_driver_library => "/root/cassandra-certs/cassandra-jdbc-wrapper-4.12.0.jar" jdbc_driver_class => "com.ing.data.cassandra.jdbc.CassandraDriver" jdbc_connection_string => "jdbc:cassandra://${host}:${port}/${keyspace}?enablessl=true&localdatacenter=${dc}" jdbc_user => "${user}" jdbc_password => "${password}" jdbc_validate_connection => true lowercase_column_names => true statement => "${statement}" record_last_run => false }``` ```` ---

> [@gadde36256](#): > > `jdbc_driver_library => "/root/cassandra-certs/cassandra-jdbc-wrapper-4.12.0.jar"` How are you running logstash? Only the root user would have access to this file and it is recommended to not run logstash as root. ---

> [@gadde36256](#): > > I have passed both lib and driver class information. OK, as described in the notes I linked to, you need to check permissions and whether the class needs the prefix. To check permissions you could trace the startup using something like ``` strace -e status=!successful ... ``` or the equivalent on whatever OS you are using. Even a successful startup will include failed system calls, but if you see a permissions error related to opening the jar that will show you something you need to fix.
