Description

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)
