src/slave/resource_estimators/fixed.cpp <https://reviews.apache.org/r/35028/#comment138565> Since the slave now asks the estimator everytime it wants to forward an update and doesn't store a cached value, it makes sense for the estimators to always respond with a value instead of a pending future. For example, if the slave gets disconnected immediately after it gets an estimate from the estimator, it might query the estimator again. src/slave/resource_estimators/fixed.cpp <https://reviews.apache.org/r/35028/#comment138562> why not let the process handle this? that way you don't have to maintain a copy? - Vinod Kone On June 3, 2015, 10:05 p.m., Jie Yu wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
