Fix it, then Ship it! src/master/master.hpp Lines 665 (patched) <https://reviews.apache.org/r/69880/#comment298350> Looking at https://github.com/apache/mesos/blob/9f6ccbd41a55846e54297ecb31fddbeee3be50c9/src/master/master.cpp#L6851-L6865 I think that this method will be called only if the agent tries to register using an already known PID (IP + port). `Master::_registerSlave()` has a comment with a bit more detail: ``` // The slave was previously disconnected but it is now trying // to register as a new slave. // There are several possible reasons for this to happen: // - If the slave failed recovery and hence registering as a new // slave before the master removed the old slave from its map. // - If the slave was shutting down while it had a registration // retry scheduled. See MESOS-8463. ``` - Gastón Kleiman On Feb. 4, 2019, 1:41 p.m., Greg Mann wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
