Subject [jira] [Commented] (YARN-4194) Extend Reservation Definition Langauge (RDL) extensions to support node labels
Date Fri, 18 Dec 2015 03:05:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15063334#comment-15063334

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
