Subject [GitHub] flink issue #2276: [FLINK-4201] [runtime] Forward suspend to checkpoint coor...

Github user StephanEwen commented on the issue:

    https://github.com/apache/flink/pull/2276
  
    I think that change is good in "our" philosophy, just wondering about the following implication:
    
    Some people want to run HA setups without ZooKeeper, simply using an external service
to make sure that the JobManager is restarted. The latest completed checkpoint is found via
a well-defined path in the checkpoint storage (rather than a well defined path in ZooKeeper).
    
    That works as an HA setup (with the exception of being susceptible to "split brain" behavior
in the presence of network partitions. 
    
    Would we interfere with such a setup when removing checkpoints on "suspend" in "standalone"
mode?
    
    BTW: We should really find a new name for "standalone" more ;-) The term is overloaded.
