----------------------------------

             Summary: Recovery of jobs on cluster restarts
                 Key: FLINK-2929
                 URL: https://issues.apache.org/jira/browse/FLINK-2929
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 0.10
            Reporter: Ufuk Celebi


Recovery information is stored in ZooKeeper under a static root like {{/flink}}. In case of a cluster restart without canceling running jobs old jobs will be recovered from ZooKeeper.

This can be confusing or helpful depending on the use case.

I suspect that the confusing case will be more common.

We can change the default cluster start up (e.g. new YARN session or new ./start-cluster call) to purge all existing data in ZooKeeper and add a flag to not do this if needed.
