> As an ops person upgrading and servicing Cassandra servers, I require a more clear message when I issue a nodetool command that the server is not ready for it so that I am not confused.
> Technical description:
> If you deploy a new binary, restart, and issue nodetool scrub/compact/updatess etc you get unfriendly assertion. An exception would be easier to understand. Also if a user has turned assertions off it is unclear what might happen. 
> {noformat}
> EC1: Throw exception to make it clear server is still in start up process.

> error: null
