How about ignoring this exception for the moment. This is an harmless error
log it seems. Until we find a proper way to fix this we can ignore this
exception. This exception occurs during the server shutdown and it does not
do any harm.
ILock lock =
primaryHazelcastInstance.getLock(HazelcastConstants.CLUSTER_COORDINATOR_LOCK);
try {
lock.lock();
isCoordinator = true;
log.info("Elected this member [" +
primaryHazelcastInstance.getCluster().getLocalMember().getUuid() + "] " +
"as the Coordinator for the cluster [" +
carbonLocalMember.getDomain() + "]");
// Notify all OSGi services which are waiting for this
member to become the coordinator
List<CoordinatedActivity> coordinatedActivities =
CarbonCoreDataHolder.getInstance().getCoordinatedActivities();
for (CoordinatedActivity coordinatedActivity :
coordinatedActivities) {
coordinatedActivity.execute();
}
*} catch (HazelcastInstanceNotActiveException ignored) {*
* // Ignoring this exception as a workaround to
https://wso2.org/jira/browse/CARBON-14887
<https://wso2.org/jira/browse/CARBON-14887>*
* } finally {*
* try {*
* lock.unlock();*
* } catch (HazelcastInstanceNotActiveException e) {*
* // Ignoring this exception as a workaround to
https://wso2.org/jira/browse/CARBON-14887
<https://wso2.org/jira/browse/CARBON-14887>*
* }*
* }*
