Hello everyone, I would like to gently ask for help in reviewing the following issue that we've been facing for a while: https://issues.apache.org/jira/browse/CASSANDRA-19760
When a cleanup command is called, the compaction process under the hood is triggered accordingly. However, if there is nothing to compact or the cleanup command returns with a status other than SUCCESSFUL, there is no way to get the execution results of the command that was run. This is especially true when using any kind of automation/scripting on top of JMX or as a nodetool wrapper. I propose to keep these history results in memory for some time and expose them via a virtual table so that a user can query it to check the status. Any suggestions are welcome. I believe other commands like verify, scrub, etc. can be exposed in the same way.
