>             Project: Kylin
>          Issue Type: Bug
>    Affects Versions: v1.5.2, v1.5.2.1
>            Reporter: Richard Calaba
>            Priority: Minor

> I have realized that if my job stops with error and I try to recover the error and resume the job - then the latest step starts again from scratch. This is fine but in my opinion the log of the Step should clear as well - now it is showing the error from my previous attempt.
> Specifically observed in #4 Step Name: Build Dimension Dictionary - but is probbaly generic issue.
> To correct this: clear the log of the Build Step after the job Step is resumed. Already when the job step is restarted, not after it is completed.
> (if Kylin fails i.e. for out of memory - it silently dies and analyzing the step log shows wrong error (from previous run) - if it would be empty -> I would know that most probable cause was that Kylin died)
