[jira] [Created] (MESOS-9282) StatusUpdateManager does not sync checkpointed data to disk.

Jie Yu created MESOS-9282:
-----------------------------

             Summary: StatusUpdateManager does not sync checkpointed data to disk.
                 Key: MESOS-9282
                 URL: https://issues.apache.org/jira/browse/MESOS-9282
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 1.7.0, 1.6.1, 1.5.1
            Reporter: Jie Yu


This is related to MESOS-9281, which we observed in a testing environment.

The status update manager used to open the checkpoint file using O_SYNC, which will guarantee that each write will be persisted to the disk (similar to calling fsync() after each write()).

This was removed due to some performance issue
https://reviews.apache.org/r/50635/

However, the assumption in the patch is no longer true after we allow the re-use the same agent ID after machine reboot. This will likely cause issues.
