Hi All, Last week we discussed the fact that configuration entries stored in Configuration Admin are currently read-only. We agreed that we should add metatype information to the configuration entries so that will be editable using the Felix webconsole. However, while describing the steps to setup a 2-node Cassandra cluster I figured that this still doesn't provide a real solution for common use cases, for several reasons:
* To setup a Cassandra cluster, some 'autobootstrap' must be set to false on node 1 and to true on one 2, prior to starting the nodes. The nodes must never be started for the first time with the incorrect autobootstrap setting. So changing the configuration in the Felix webconsole won't do; that's just too late. * You cannot always access the Felix webconsole without the proper hostname and portnr defined prior to starting Amdatu, as the default port may already be occupied by another service. When the http service cannot be started, of course I cannot enter the Felix web console to change the configuration entries to the proper values. In my case I run the nodes on a Linux server and cannot access the httpservice as long as it tries to listen to the default hostname 'localhost' and port '8080'; it will fail with an 'address already in use' since 8080 is usually already taken by another service. The only possible solution I see right now is replacing the filebased config bundle with fileinstall (yes, there it is again). In this case config files are stored on disk and can be changed to the proper values prior to starting Amdatu for the first time. I know that there is a lot of resistance against the use of fileinstall, but are there any better alternatives?
