I am trying to create a simple client with pykafka. For this I need SSL certificates. The client runs under RHEL 7 and Python 3.6.x It looks like the connection works but I don't get any feedback or data, only a black screen. How can I check the connection or get error messages.
#!/usr/bin/scl enable rh-python36 -- python3
from pykafka import KafkaClient, SslConfig
config = SslConfig(cafile='key/root_ca.crt',
certfile='key/cert.crt',
keyfile='key/key.key',
password='xxxx')
client = KafkaClient(hosts="xxxxxxx:9093",
ssl_config=config)
print("topics", client.topics)
topic = client.topics['xxxxxx']
consumer = topic.get_simple_consumer(
consumer_group="yyyyy",
auto_offset_reset=OffsetType.EARLIEST,
reset_offset_on_start=False
)
for message in consumer:
if message is not None:
print (message.offset, message.value)
