Spark-Vertica access issue (connects, prints schema, count but not able to get the records) - scala

Question

I am able to connect to Vertica through EMR (Spark), count and print schema but not able to read the data. Able to telnet from EMR.
My Vertica version
Vertica Database
09.02.0104
vertica.jar
09.01.0100
Spark-shell command
spark-shell --jars /home/hadoop/vertica-9.0.1_spark2.1_scala2.11.jar,/home/hadoop/vertica-
jdbc-9.0.1-7.jar
Query to read the Vertica table
val source = spark.read.format("com.vertica.spark.datasource.DefaultSource").option("host",
"verticaHost").option("port", "port").option("db", "DataBase?ssl=true").option("dbschema",
"Schemna").option("user", "user").option("password", "password").option("table",
"table").option("numPartitions", "1").option("queryTimeout", "500").load()
I also added .option("query", "select * from schema.table limit 100") and counted but it gave full count of the table instead of 100.
Output
source.printSchema() --> works, gets the schema information
source.count() --> works, gets the count.
source.show() --> Throws below error.
