Kafka source vs Avro source for reading and writing data into kafka channel using flume


Kafka source vs Avro source for reading and writing data into kafka channel using flume

I wish this help you In Flume, the Avro RPC source binds to a specified TCP port of a network interface, so only one Avro source of one of the Flume agents running on a single machine can ever receive events sent to this port.
Avro source is meant to connect two or more Flume agents together: one or more Avro sinks connect to a single Avro source.

it fixes the issue You can solve this error by providing the flume-env.sh file with the path to a zookeeper jar. After that just restart your agent and you should see the info from your Kafka topic flowing.
code :
FLUME_CLASSPATH="/path/to/hadoop-2.5.0-cdh5.3.1/share/hadoop/common/lib/zookeeper-3.4.5-cdh5.3.1.jar"
How to use Flume's Kafka Channel without specifying a source

like below fixes the issue After digging around a bit I noticed that Ambari didn't create any flume conf files for the specified agent. Ambari seems to only create/update the flume config if I specify test.sources = kafka-source. Once I added this into the flume config (via ambari) the config was created on the box and the flume agent started successfully.
The final flume config looked like this:
code :
test.sources=kafka-source
test.channels = kafka-channel
test.sinks = hdfs-sink

test.channels.kafka-channel.type = org.apache.flume.channel.kafka.KafkaChannel
test.channels.kafka-channel.kafka.bootstrap.servers = localhost:9092
test.channels.kafka-channel.kafka.topic = test
test.channels.kafka-channel.parseAsFlumeEvent = false

test.sinks.hdfs-sink.channel = kafka-channel
test.sinks.hdfs-sink.type = hdfs
test.sinks.hdfs-sink.hdfs.path = hdfs:///data/test

will be helpful for those in need So the problem was from Kafka Consumer. It receives the full message from flume
code :
Interceptor + some garbage characters + message
Is it possible to use Flume Kafka Source by itself?

To fix this issue Yes, you can. In general, what a Kafka consumer can or cannot do is fully independent on who produced the data, but only on the format in which the data has been encoded.
That is the whole point of Kafka and Enterprise Service Bus.

this will help to the observatoins from the user pissall I was able to solve the issue. It was a version issue. I got it to run by running pyspark from the terminal with the following command:
code :
!pyspark --packages org.apache.spark:spark-sql-kafka-0-10_2.11:2.4.4
