>
> *Summary*
> Some tests are validating situation, when node (or cluster) does not start 
> correctly.
> They rely on `TimeoutError` to be raised, but technically it is also possible 
> that `ccm` will raise `NodeError` without waiting for timeout to be met.
> *Why we need this change*
> We can improve `ccm` to fail fast in case node being started terminates. This 
> would:
>  * make unexpected test failures faster to fail (not waiting 90 or 120s)
>  * shorten overall test duration, even if timeout is given
> ccm work (in progress): https://github.com/riptano/ccm/pull/724
> *Proposed improvement*
> Handle both TimeoutError and NodeError as expected node failure.
> *PR*
