Subject Camel Hazelcast Component creating multiple instances of Hazelcast
Date Tue, 17 Mar 2015 15:26:35 GMT

I have started using Camel Hazelcast for distributed caching but realised
that all the bundles using the Camel hazelcast component create a new
instance of Hazelcast. So 11bundles will result in 11 members joined in in
one single JVM and the list is growing.

Is this a healthy thing - see below hazelcast log? Hazelcast documentation
doesn't explicitly says how many members you should have per JVM. I am
inclined to think it should be limited to small number or even to one
member per JVM.

Camel Hazelcast component does not have support for joining an already
running instance of Hazelcast, I think it should.

Any ideas how best to set up hazelcast/camel in one single JVM would be
very much appreciated.
