-----------------------------
Summary: Embedded Zookeeper has missing OSGi import, can't use
camel-kafka
Key: SM-3956
URL: https://issues.apache.org/jira/browse/SM-3956
Project: ServiceMix
Issue Type: Bug
Components: features
Affects Versions: 7.0.1, 7.1.0
Environment: JRE 8 update 172. Windows 10.
Kafka in docker (wurstmeister/kafka) and kafka on Win Server using quickstart
scripts. Both give same issue.
feature:install camel-kafka
route info for the Camel 2.16 URL notation:
{code:java}
<from id="Kafka"
uri="kafka:localhost:9092?topic=test&groupId=testing&zookeeperHost=localhost&zookeeperPort=2181"/>
<to id="fileout" uri="file://c:/esb/kafkaconsumer"/>
{code}
Reproduced on 7.0.1 and 7.1.0 (20190113.134104-3)
Bug does not appear in Talend ESB which uses Camel 2.17 with alternate Kafka
implementation
Reporter: Charles F
I'm trying to use a camel-route that would take a message from a Apache Kafka
instance.
Instead of an active route I get an exception that appears to come from the
zookeeper system bundle.
{code:java}
java.lang.NoClassDefFoundError: org/ietf/jgss/GSSException
at
org.apache.zookeeper.ClientCnxn$SendThread.startConnect(ClientCnxn.java:945)[99:org.apache.hadoop.zookeeper:3.4.6]
at
org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1003)[99:org.apache.hadoop.zookeeper:3.4.6]
Caused by: java.lang.ClassNotFoundException: org.ietf.jgss.GSSException not
found by org.apache.hadoop.zookeeper [99]
{code}
That error is consistent with Zookeeper bug ZOOKEEPER-1942 (and possibly 2056)
as a malformed OSGi manifest. Jira tickets mention a patch or later version
with fix.
I've tried using OSGi wrap: and fragments for the org.ietf.jgss package without
success, against the zookeeper provided bundle and the zkclient camel
dependency.
Camel route declared as active in bundle list, with secondary error message
preceding activation in servicemix log:
{code:java}
BlueprintCamelContext | 40 - org.apache.camel.camel-blueprint - 2.16.5 | Error
occurred during starting Camel: CamelContext(context1) due Unable to connect to
zookeeper server within timeout: 6000
org.I0Itec.zkclient.exception.ZkTimeoutException: Unable to connect to
zookeeper server within timeout: 6000
