Vinod Kone created MESOS-614:
--------------------------------
Summary: Master should remove checkpointing slave that gets
disconnected when the new slave tries to register
Key: MESOS-614
URL: https://issues.apache.org/jira/browse/MESOS-614
Project: Mesos
Issue Type: Improvement
Reporter: Vinod Kone
Assignee: Vinod Kone
Fix For: 0.13.0
When a checkpointing slave is not able to recover (for whatever reason) it
tries to register as a new slave. But if this registration happens before
master has removed the old slave, the master simply gives the old slave id for
the new slave. This means the master thinks the slave is running a bunch of
tasks whereas the slave thinks it is new.
Master should remove the slave from its map (send TASK_LOST updates) when this
happens and create a new slave entry.
