Subject [jira] [Commented] (YARN-3251) CapacityScheduler deadlock when computing absolute max avail capacity
Date Tue, 24 Feb 2015 17:30:05 GMT

Wangda Tan commented on YARN-3251:
----------------------------------

Thanks for reporting this, [~jlowe]!

Since this is a blocker for 2.7, I will create a patch for this using method described in
YARN-3243 first before working on other related refactorings, I added this as a sub task of
YARN-3251.
