Nick Doan commented on CASSANDRA-21093:
---------------------------------------

Thank you, I wasn't aware that this option existed. If I understand correctly, 
this requires extra work on the consumer side to declare META-INF, which I 
assume shouldn't be a problem. We probably also want to add a custom check type 
to `StartupCheckType`

> {{Currently, the list of available startup checks is fixed for a given 
> distribution. Users can optionally override whether a check type is executed 
> using {_}startup_checks{_}.}}
>  
> In some deployment environments, users may want to have additional checks in 
> place, but currently, this would require running these checks separately 
> before launching the Cassandra daemon. Can we potentially add support for 
> {_}custom_startup_checks{_}, which takes a list of classes to be dynamically 
> loaded at runtime from classpath? Alternatively, if custom deployments wraps 
> CassandraDaemon, we can also consider exposing startup checks as a public 
> singleton so that the wrapper can register additional startup checks.
