```
2024-04-23 01:08:22,107 ERROR [main] log.GlueLogger (GlueLogger.scala:error(7)): ERROR: Detected connectivity issue. Check the reference conf file/Glue connection for the source, the job is aborted java.io.IOException: Failed to open native connection to Cassandra at Profile based config at CassandraConnector.conf :: Error instantiating class com.aws.ssa.keyspaces.throttler.AmazonKeyspacesFixedRateThrottler (specified by advanced.throttler.class): Detected a synchronous API call on a driver thread, failing because this can cause deadlocks.
