Kapil Arya created MESOS-3388:
---------------------------------
Summary: Add an interface to allow Slave Modules to
checkpoint/restore state.
Key: MESOS-3388
URL: https://issues.apache.org/jira/browse/MESOS-3388
Project: Mesos
Issue Type: Bug
Reporter: Kapil Arya
* This is to restore module-specific in-memory data structures that might be
required by the modules to do cleanup on task exit, etc.
* We need to define the interaction when an Agent is restarted with a different
set of modules.
One open question is how does an Agent identify a certain module? One
possibility is to assign a UID to the module and pass it in during `create()`?.
The UID is used to assign a ckpt directory during ckpt/restore. (Something like
/tmp/mesos/.../<slaveID>/modules/<module UID>).
