> As related in drill user mailing list 
> ([http://mail-archives.apache.org/mod_mbox/drill-user/201904.mbox/%3ceec5a6bc-fa95-44ce-d2b6-c02c1bfd0...@laposte.net%3e])
> It's possible to configure any system option of Drill (sys.option) in the 
> drill-override.conf.
>  Exemple with _drill.exec.storage.file.partition.column.label_
> {code:java}
> drill.exec: {
>   cluster-id: "drillbits-test",
>   ...
> },
> drill.exec.options: {
>   drill.exec.storage.file.partition.column.label: "drill_dir",
>   ...
> }
> {code}
> But the configuration of the particular option *store.parquet.use_new_reader* 
> in the same way has absolutly no effect.
> Have no idea if this in rapport  with the "Not supported in this release" 
> description found for this option, but it's appears at minimal strange that 
> it's possible to configure it with ALTER SESSION/SYSTEM and not in 
> drill-override.conf
> As an additional point, I had a little trouble finding that the options had 
> to fit into *drill.exec.options:* so I propose to add in 
> drill-override-example.conf a sample of configuration of any option to avoid 
> this trouble.
> Even with keeping the mention found in drill-module.conf if necessary
> {code:json}
> # Users are not supposed to set these options in the drill-override.conf file.
> # Users should use ALTER SYSTEM and ALTER SESSION to set the options.
> {code}
