-----------------------------------------
I think this one's a blocker for the 1.1 release.
> HA recovery not working properly under ApplicationMaster failures.

> Key: FLINK-4182

> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination, State Backends, Checkpointing
> Affects Versions: 1.0.3
> Reporter: Stefan Richter
>
> When randomly killing TaskManager and ApplicationMaster, a job sometimes does
> not properly recover in HA mode.
> There can be different symptoms for this. For example, in one case the job is
> dying with the following exception:
> {code}
> The program finished with the following exception:
> org.apache.flink.client.program.ProgramInvocationException: The program
> execution failed: Cannot set up the user code libraries: Cannot get library

> In other cases, i noticed inconsistencies in the results by testing with a
> streaming state machine job and a Kafka source. My guess is that value state
> is no restored properly, because all invalid transactions in the log start
> from the initial state, which is the default value for the value state.
