Charles F commented on SM-3956:
-------------------------------
Some further details hidden in Environment Jira field, pasted here for
visibility:
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
> Embedded Zookeeper has missing OSGi import, can't use camel-kafka

> 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
