Hello - I have a use case where I need to run the Cassandra Server as an OSGi bundle. I have been able to embed all of the Cassandra dependencies in an OSGi bundle and run it on Karaf container, but I am not happy with the approach I have thus far.
Since CassandraDaemon has System.exit() calls in it, if these execute it will bring down my entire OSGi container rather than just the bundle Cassandra is running in. I hacked up a copy of CassandraDaemon enough to get it to run in the bundle with no System.exit() calls, but the Cassandra StorageService is not "aware" of it, i.e., I cannot call the StorageService.registerDaemon(...) method because my copy of CassandraDaemon does not extend Apache's. hence I am getting exceptions when I do shutdown my container or restart the bundle because the StorageService and my CassandraDaemon are not "linked". I am considering trying to extend Apache's CassandraDaemon and override its setup() method with a SecurityManager that disables System.exit() calls. This too sounds "hacky". Does anyone have any better suggestions? Or know of an existing open source project that has successfully embedded CassandraServer in an OSGi bundle? I am using Cassandra v2.0.7 and am currently using CQL (vs. Thrift). Thanks - Hugh
