问题
I need to route ActiveMQ messages to Kafka(Cloudera) using Camel using authentication protocol Kerberos.
- ActiveMQ v5.15.4
- Camel:2.21.1
- Kafka Clients: 1.1.0
- Server Version: Apache/2.4.6(CentOS)
Kafka Security documentation states that it only supports SASL_PLAINTEXT and
SASL_SSL for Kerberos
On the other hand when I try to use SASL_PLAINTEXT for security protocol in Camel I am getting an error during the ActiveMQ starting. As a result ActiveMQ will not start.
I took the latest Camel code from: https://github.com/apache/camel.git and it states that it only supports SSL and PLAINTEXT as security protocols values.
I did find this solved issue: https://access.redhat.com/solutions/3364871 but I did not find any evidence that this is working in the latest Camel version.
My Camel setup fragment is:
<log message="Started The Producer Route" />
<to uri="kafka://10.100.70.00:9092?topic=MyEvents.s1.v1&brokers=10.100.70.00:9092&requestTimeoutMs=305000&retries=3&keySerializerClass=org.apache.kafka.common.serialization.ByteArraySerializer&saslMechanism=GSSAPI&serializerClass=org.apache.kafka.common.serialization.ByteArraySerializer&securityProtocol=SASL_PLAINTEXT&saslKerberosServiceName=kafka"/>
I am using an external Jaas configuration file.
Is it true that Camel does not support SASL_PLAINTEXT?
回答1:
Camel supports SASL_PLAINTEXT as it uses Kafka client v1.1.0. The problem is that the actual security parameter is not propagated to the Camel interface. That means the parameter is not recognised during ActiveMQ startup. I've opened issue for this problem.
