Benjamin Mahler commented on MESOS-7478:
----------------------------------------
[~anandmazumdar] aside from my manual testing, I ran the upgrade script. It
turns out it doesn't catch it because it upgrades the master first, then
agents. Filed MESOS-7483.
> Pre-1.2.x master does not work with 1.2.x agent.

> This appears to have been due to a lack of manual upgrade testing (we also
> don't have any automated upgrade testing in place).
> The check in {{getExecutorInfo(...)}}
> [here|https://github.com/apache/mesos/blob/1.2.0/src/slave/slave.cpp#L4609]
> crashes with an old master because it occurs before our injection in
> {{run(...)}}. See the {{runTask(...)}} call into {{getExecutorInfo(...)}}
> [here|https://github.com/apache/mesos/blob/1.2.0/src/slave/slave.cpp#L1556].
