I am able to get the metadata of the table but as when I try to show the data using "df.show()" it fails and give this below error:

org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 0.0 failed 1 times, most recent failure: Lost task 0.0 in stage 0.0 (TID 0, localhost, executor driver): java.sql.SQLNonTransientConnectionException: [Vertica]VJDBC Failed to connect to host on port 5433.
