Kafka not loading data for json input

I am trying to load json data using vkconfig but not able to do so . It just doesn't load the data into the target table. Don't see any error as well.  Here is what i did. 

-- create scheduler 

dbadmin> /opt/vertica/packages/kafka/bin/vkconfig scheduler --add --brokers 10.90.84.122:9092 --conf config.properties

Warning: no operator was given. Kafka Scheduler can only be used by dbadmin or the operator. Use "--edit" to add an operator to a created scheduler in the future.

## Since i am using dbadmin so i can ignore it. My config.properties file includes jdbc parameter and config-schema "test_kafka". There is no error regarding jdbc connection 

--create topic , i have topic named vert-test already created in kakfa broker

dbadmin> /opt/vertica/packages/kafka/bin/vkconfig topic --add --target public.tbl_kafka_test --topic vert-kafka --rejection-table public.tbl_rejection --parser KafkaJSONParser --conf config.properties

--  kafka-topic "vert-kafka" exists in kafka-broker

root>bin/kafka-topics.sh --list --topic vert-kafka --zookeeper 10.90.84.122:2181
vert-kafka

--The json input format I am trying to load 

{"name":"zum","description":"Zum.com","level1":"Web"}
{"name":"zynga","description":"Zynga.com","level1":"Web"}

-- Here is the kafka tables created inside schema "test_kafka"

The output table is flex table . There are no records inserted :

dbadmin=> select * from public.tbl_kafka_test;
