URL: https://github.com/apache/camel-kafka-connector-examples/issues/336
First, thank you so much for creating these excellent Camel libraries.
Second, this may not be the right place to put this question. I don't have
an issue with the connector. My inexperience is the real issue.
Background: I'm wanting to sink a JSON message from a Kafka (open-source)
topic to Cassandra (open-source) table with Kafka Connect
Kafka
Version: 2.13-3.0.0 (Scala: 2.13, Kafka: 3.0.0)
IP/Ports: 10.188.5.86:9092,10.188.5.86:9093,10.188.5.86:9094
Topic: pie (./bin/kafka-topics.sh --bootstrap-server
10.188.5.86:9092,10.188.5.86:9093,10.188.5.86:9094 --create
--replication-factor 1 --partitions 1 --topic pie)
JSON
Simple Pie Data:
{"Type:":"Apple","Invented":1381}
{"Type:":"Pecan","Invented":1870}
{"Type:":"Cherry","Invented":1500}
Cassandra
Version:4.0.3
IP:10.66.16.10
Port:9042
User:cameldevloader
Pass:newpassword
CREATE TABLE pie(type varchar, invented double, PRIMARY KEY (type));
INSERT INTO pie (type, invented) VALUES ('Chess',1750);
SELECT * FROM pie;
yields: Chess 1750.0
Kafka Connect
Using this Camel connector:
https://camel.apache.org/camel-kafka-connector/1.0.x/reference/connectors/camel-cassandra-sink-kafka-sink-connector.html
Downloaded from:
https://repo.maven.apache.org/maven2/org/apache/camel/kafkaconnector/camel-cassandra-sink-kafka-connector/1.0.0/camel-cassandra-sink-kafka-connector-1.0.0-package.tar.gz
copied the camel-cassandra-sink-kafka-connector-1.0.0-package.tar.gz to
Kafka server at location
/root/sofware/camel-cassandra-sink-kafka-connector-1.0.0-package.tar.gz
on my Kafka server in the /root/connectors/ directory unzipped:
~/connectors/tar -xvzf
../software/camel-cassandra-sink-kafka-connector-1.0.0-package.tar.gz
Updated /root/kafka/config/connect-standalone.properties

# Set to a list of filesystem paths separated by commas (,) to enable class
loading isolation for plugins
# (connectors, converters, transformations). The list should consist of top
level directories that include
# any combination of:
# a) directories immediately containing jars with plugins and their
dependencies
# b) uber-jars with plugins and their dependencies
# c) directories immediately containing the package directory structure of
classes of plugins and their dependencies
# Note: symlinks will be followed to discover dependencies or plugins.
# Examples:
plugin.path=/root/connectors/`
