[jira] [Created] (COTTON-6) Leverage Mesos persistent volumes to retain the state of failed instances.

Yan Xu created COTTON-6:
---------------------------

             Summary: Leverage Mesos persistent volumes to retain the state of failed instances.
                 Key: COTTON-6
                 URL: https://issues.apache.org/jira/browse/COTTON-6
             Project: COTTON
          Issue Type: Task
            Reporter: Yan Xu


With this feature Cotton scheduler can ask Mesos to run the a new instance of mysqld and recover the work directory left by the previously failed instance. This requires the host that the work dir is on remains online. If it is not, the new instance needs to be launched onto a new host and recover from the HDFS snapshot.
