Summary: Agent failure during recovery prevents reregistration
Key: MESOS-5635
URL: https://issues.apache.org/jira/browse/MESOS-5635
Project: Mesos
Issue Type: Bug
Reporter: Greg Mann
This issue was observed recently on an internal test cluster. Due to a bug in
the agent code (MESOS-5629), regular segfaults were occurring on an agent.
While the agent was recovering from one of these failures, it segfaulted again.
After this time, we noticed that after recovery, the agent did not print
{{Finished recovery}}, and its logs did not show any indication of
reregistering with the master. Looking at the master's logs, however, the
following line was observed repeatedly, at intervals on the order of seconds:
{code}
W0617 21:27:07.010679 2016 master.cpp:4773] Agent
2b899dd3-3b1f-4520-a6b2-98e32196f723-S4 at slave(1)@10.10.0.87:5051
(10.10.0.87) attempted to re-register after removal; shutting it down
{code}
These re-registration attempts had no corresponding lines in the agent log.
Subsequently deleting the contents of the agent's {{work_dir}} and restarting
it led to a successful registration with a new agent ID:
{code}
