IT23721: MQTT/KAFKA CLASSLOADING ERRORS FROM BROKERS CREATED FROM IIB V10FP10 OR IIB V10 FP11 FIXPACKS

APAR status

• Closed as program error.

Error description

• The jarsURL property value of MQTT/Kafka configurable service
  get set as  <IIB_Installation>/server/connectors/mqtt or
  <IIB_Installation>/server/connectors/kafka if the broker is
  created from an IIB V10 FP10 or V10 FP11 fixpack. For example
  the value set as
  /opt/ibm/mqsi/iib-10.0.0.10/server/connectors/mqtt if the broker
  is created from a V10 FP10 environment. Then if the same broker
  is started from a V10 FP11 IIB environment then the loading of
  MQTT and Kafka connectors can fail with following error messages
  in the broker syslog  file.
  
  BIP3849E: Failed to load the Connector 'Kafka'.
  
  BIP3847E: The Connector provider class
  'com.ibm.broker.connector.kafka.KafkaConnectorFactory' can not
  be found  in the jarsUrl path
  '/opt/ibm/mqsi/iib-10.0.0.10/server/connectors/kafka', in the
  shared classes directory or in the classpath.
  
  BIP3849E: Failed to load the Connector 'MQTT'.
  
  BIP3847E: The Connector provider class
  'com.ibm.broker.connector.mqtt.MQTTConnectorFactory' can not be
  found in the jarsUrl path
  '/opt/ibm/mqsi/iib-10.0.0.10/server/connectors/mqtt', in the
  shared classes directory or in the classpath.
  

Local fix

• Correct the jarsURL property value by running the following
  commands and then restart the broker.
  
  mqsichangeproperties BKRName -c ConnectorProviders -o MQTT -n
  jarsURL -v ''
  
  mqsichangeproperties BKRName -c ConnectorProviders -o Kafka  -n
  jarsURL -v ''

  PROBLEM DESCRIPTION:
  The jarsURL property value of MQTT/Kafka configurable service
  gets set as  <IIB_Installation>/server/connectors/mqtt or
  <IIB_Installation>/server/connectors/kafka instead of value
  'default_Path' if the broker is created from an IIB V10 FP10 or
  V10 FP11 fixpack. For example the value set as
  /opt/ibm/mqsi/iib-10.0.0.10/server/connectors/mqtt if the broker
  is created from a V10 FP10 environment. Then if the same broker
  is started from a V10 FP11 IIB environment then the loading of
  MQTT and Kafka connectors can fail with following error messages
  in the broker syslog file.
  
  BIP3849E: Failed to load the Connector 'Kafka'.
  
  BIP3847E: The Connector provider class
  'com.ibm.broker.connector.kafka.KafkaConnectorFactory' can not
  be found  in the jarsUrl path
  '/opt/ibm/mqsi/iib-10.0.0.10/server/connectors/kafka', in the
  shared classes directory or in the classpath.
  
  BIP3849E: Failed to load the Connector 'MQTT'.
  
  BIP3847E: The Connector provider class
  'com.ibm.broker.connector.mqtt.MQTTConnectorFactory' can not be
  found in the jarsUrl path
  '/opt/ibm/mqsi/iib-10.0.0.10/server/connectors/mqtt', in the
  shared classes directory or in the classpath.
  

Problem conclusion

• The product now sets correct value for jarsURL property of
  MQTT/Kafka configurable services.
