Jack Crawford created MESOS-7771:
------------------------------------
Summary: mesos master continually forwards status updates for
finished tasks
Key: MESOS-7771
URL: https://issues.apache.org/jira/browse/MESOS-7771
Project: Mesos
Issue Type: Bug
Reporter: Jack Crawford
I run a cluster of 50-100 machines with a single mesos master. Occasionally,
the master will get into a state where it will continually forward status
updates for the same tasks until all work on the cluster grinds to a halt.
Checking the logs, i see numerous `Forwarding status update TASK_FINISHED ...`
messages for the same task id. Additionally, the "Active Tasks" section of the
web ui gradually begins to entirely list tasks in finished/failed states,
instead of staging/running
Im not sure what causes this, but it appears to occur rarely when the cluster
is under heavy scheduling load (100s to 1000s of jobs scheduled in <1min
sometimes)
