--------------------------------
Summary: Master does not handle returning unreachable agents as
draining/deactivated
Key: MESOS-9934
URL: https://issues.apache.org/jira/browse/MESOS-9934
Project: Mesos
Issue Type: Bug
Components: master
Reporter: Joseph Wu
Assignee: Joseph Wu
The master has two code paths for handling agent reregistration messages, one
culminating in {{Master::___reregisterSlave}} and the other in
{{Master::}}{{__reregisterSlave}}. The two paths are not continuations of each
other. Looks like we missed the double-underscore case in the initial
implementation. This is the path that unreachable agents take, when/if they
come back to the cluster. The result is that when unreachable agents are
marked for draining, they do not get sent the appropriate message unless they
are forced to reregister again (i.e. restarted manually).
