I have been working on CASSANDRA-18661 to see if it is possible to migrate to the Apache commons-cli as noted in the ticket. It is possible to do so, and after several pull requests to commons-cli, I have managed to migrate the settings of the stress tool. We will have to wait for commons-cli 1.7.0 to be released before we can merge this change into the trunk. However, I thought it expedient to discuss a few items before that pull request is made.
1. The original options were serializable the apache-cli based ones are not. I think this was to support thrift and is no longer necessary. I would like to remove the Serializable interface from the options. If this is not possible, extra work will need to be done to ensure that serialization will work. 2. There has been some discussion on the ticket about legacy scripts using the original options making this a breaking change. It should be possible to deploy the same functional stress test with the two different command line interfaces. This will take some extra work. The net result is that the changes are only in the command line and do not impact the operation once the options have been set. Finally, there were few tests that showed what the various options were doing. I have written tests for all the new settings implementations. I think that we we keep 2 interfaces it would be possible and advisable to modify the command line tests to support both CLIs. If you are interested to see what the new CLI options are, I have pasted the output of a help command into the jira ticket. Thank you for your time, Claude
