Hi, MESOS-2375 removed the checkpoint flag from "slave/flags.hpp" as MESOS-2317/MESOS-444 already made it unavailable from the command line and all slaves are checkpointing slaves.
As a result the below—previously common—pattern in test code is incorrect/unnecessary. // Setup recovery slave flags. flags.checkpoint = true; // Incorrect as flag.checkpoint does not exist anymore (as all slaves are checkpointing). flags.recover = "reconnect"; // Unnecessary, being the default value. flags.strict = true; // Unnecessary, being the default value. Please note this when writing new tests and update reviews which are currently in flight. Thanks and regards, Joerg
