`markingUnreachable` is a transient collection; at present we just need it for `CHECK`s. Right now, `removed` includes both unreachable agents and agents that have gracefully shutdown. I think we should clean that up (e.g., get rid of `removed` entirely if possible and add a separate `unreachable` map), but I'd prefer to handle that in a later review, since the GC work will introduce an `unreachable` map anyway. > On Aug. 23, 2016, 12:56 a.m., Vinod Kone wrote: > > src/master/master.hpp, line 1700 > > <https://reviews.apache.org/r/50705/diff/4/?file=1472657#file1472657line1700> > > > > Should this still be called `removed` ? See discussion elsewhere about `removed` containing both "shutdown" and "unreachable" agents. - Neil ----------------------------------------------------------- This is an automatically generated e-mail.
