> 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:

> The program finished with the following exception:

> 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.
