Drill does not guarantee backward compatibility between versions, especially when doing downgrade. For this case, you need to clean up your environment first and then start 1.13 version.

> Hi Team,
> We meet an issue after we downgrade from 1.15 to 1.13.
> When we query sys.option, it shows this error. 
> Error: VALIDATION ERROR: The option 'drill.exec.hashjoin.fallback.enabled' does not exist.
> Fragment 0:0
>  
> Here is what we did.
>  # upgrade to 1.15. unzip then soft link the dill_home to 1.15 folder. 
>  # change parameter drill.exec.hashjoin.fallback.enabled to true in system level.
>  # downgrade by soft link the drill_home to 1.13 folder.
> it seems different versions using the same parameter file.
> Could you please check this?
