Question regarding effect of 'restart-strategy: none' on Flink (1.4.1) JobManager HA

[Jash, Shaswata (Nokia - IN/Bangalore)]

Hello Flink-Experts,

 

I am observing that even after setting ‘restart-strategy: none’ with Flink JobManager HA (High Availability) setup, JobManager is still continuing restarting the ongoing jobs after failover. Is it the expected behavior? Jobs have not used any checkpoint/savepoints. My understanding was – JobManager HA along with other than no restart strategy will only ensure job be will resubmitted by the new JobManager after failover. I am using FLink 1.4.1.

 

Can you please share your views?

Hi Shaswata,

are you using a standalone Flink cluster or how does your deployement look like? E.g. YARN has its own restart attempts [1].

Hi Timo,

My observation was based on standalone cluster.
