-----------------------------------------
Hi [~sihuazhou], I tried restarting the cluster again and submitted the job
again with MemoryStateBackend and it seems to be working fine with a single TM
now. Strange that it does not work always.

> HI,
> I have set up a flink 1.4 cluster with 1 job manager and two task managers.
> The configs taskmanager.numberOfTaskSlots and parallelism.default were set
> to 2 on each node. I submitted a job to this cluster and it runs fine. To
> test fault tolerance, I killed one task manager. I was expecting the job to
> run fine because one of the 2 task managers was still up and running.
> However, the job failed. Am I missing something?
