Alexey Tumanov commented on YARN-4194:
--------------------------------------
Carlo, Subru, thanks for your review. I'll add documentation.
Carlo, I took a quick look at
ReservationInputValidator.validateReservationDefinition() . It checks boundary
conditions on numerical fields of the resDef. For the new String node label
expression field, the best validation we can do requires parsing code for OR
expressions, which is in the works. If we decide it's a good idea to parse HRDL
node label expression at validation time, it would probably be best to
synchronize that code change with the new OR expression parser.
Thanks,
Alexey
