Anindya Sinha updated MESOS-5448:
---------------------------------
Description:
When the master sends a CheckpointResourcesMessage to the agent, the agent
attempts to rmdir the persistent volume for a DESTROY operation (if it existed
before, and is no longer in the updated checkpoint in
CheckpointResourcesMessage).
If the slave restarts before the operation finishes, the disk space can be
leaked because a reattempt of a rmdir is not done (since the checkpoint is
already updated).
Subsequently, a CREATE on the same path could result in leaking of the data to
another framework (since the directory was not rm-ed) since the CREATE
operation is successful even if the root directory exists and the contents of
that directory is not empty.
