> Key: FLINK-2287
> URL: https://issues.apache.org/jira/browse/FLINK-2287
> Project: Flink
> Issue Type: Improvement
> Components: JobManager, TaskManager
> Reporter: Ufuk Celebi
> Fix For: 0.10

>
> The problem: The JobManager (JM) is a single point of failure. When it
> crashes, TaskManagers (TM) fail all running jobs and try to reconnect to the
> same JM. A failed JM looses all state and can not resume the running jobs;
> even if it recovers and the TMs reconnect.
> Solution: implement JM fault tolerance/high availability by having multiple
> JM instances running with one as leader and the other(s) in standby. The
> exact coordination and state update protocol between JM, TM, and clients is
> covered in sub-tasks/issues.
