Subject Re: Branch merges and 3.0.0-beta1 scope
Date Fri, 25 Aug 2017 19:31:32 GMT
Hi Andrew,

Thanks for starting the discussion - we have a feature YARN-5734 for API
based scheduler configuration that I feel is pretty close to merge (also "a
few weeks"). It's almost completely code and API additions and we were
careful to design it so that it's compatible (feature is also turned off by
default). Hoping to get this in before 3.0.0-GA. Just wanted to send this
note so that we are not caught off guard by this feature.

Thanks!


Jonathan Hung
